Diagnose / Pastel
Pastel mistakes
Dry pigment sticks; needs surface tooth. Light pressure first; fix between layers sparingly.
23 faults, most common first
- Copying every detail of a reference without simplifyingThe drawing is filled with high-contrast, tiny marks spread uniformly across every square centimetre. Rescue
- Dust smudging and falling pastelLoose powder cascades down the work surface whenever a stroke is made. Rescue
- Early layers pressed too hard leaving no toothThe paper surface has become slick, shiny, and greasy-looking, refusing to accept any fresh pastel layers. Partly
- Fur drawn as outline scribbles instead of directional massesThe animal's silhouette is covered in frantic zigzag scribbles meant to indicate fur. Partly
- Nose outlined instead of modelled with shadow shapesThe bridge and nostrils of the nose are drawn with hard, dark perimeter lines. Rescue
- Not checking work in a mirror or at a distanceA portrait or figure exhibits an unintended tilt, an eye sitting higher than its partner, or an overall drift to one side. Rescue
- Subject has no focal pointThe canvas contains equal amounts of detail, contrast, and sharp edges everywhere. Rescue
- Trees drawn as lollipops: outline plus scribbled leavesThe tree is drawn as a straight, brown or grey stick topped with a circular contour filled with uniform scribbles. Partly
- Animal legs drawn from memory with wrong jointsThe rear legs of a four-legged animal bend forward like human knees or resemble straight sticks. Partly
- Colour palette fights: unplanned mix of many chromasThe painting features high-intensity, pure pigment across every corner without a clear dominant hue. Rescue
- Composition cut off at awkward placesLimbs, joints, or primary objects hit the boundary of the page in an awkward manner. Partly
- Dead eyes: no highlight, no eyelid shapeThe eye appears as an unvaried black disk without curvature, highlights, or distinct lid rims. Rescue
- Fixative darkening coloursDelicate highlights, aerial haze, and soft tints lose their luminosity. Partly
- Hard strokes never blended or layeredIndividual pastel strokes sit side by side as hard, isolated lines without forming continuous forms. Rescue
- Landscape with no foreground, middle or background planesThe drawing lacks spatial depth because elements at different distances share the same size, detail, and contrast. Rescue
- Local colour only: ignoring reflected light and temperatureThe object is painted using only its local hue mixed with black for shadow and white for highlight. Rescue
- Paper too smooth and clogged with pigmentThe paper surface appears slick and burnished, unable to hold further layers of pastel. Partly
- Skin looks chalky from heavy white pastelThe face has lost its natural warmth and translucency, appearing greyish or powdery like plaster. Partly
- Sky painted with one flat blueThe sky has been filled in with a single uniform shade of blue from top to bottom. Rescue
- Stopping too early because it looks fine in the phone photoThe physical artwork appears faint, lacking rich darks and crisp details, despite reading clearly when photographed. Rescue
- Tangents: edges kissing awkwardlyTwo distinct edges in the picture touch exactly at their borders without clear overlap. Rescue
- Framing wrongly: cropped or overmattedThe outer border of the frame or mat cuts directly into the subject matter, leaving no margin for the composition to breathe. Rescue
- Shapes all similar in sizeThe masses, light patches, or negative spaces across the work are all roughly the same dimensions. Rescue

Checklist: check your work against these
Each line is the quick test from the matching page. Print this page for a studio checklist.
- Copying every detail of a reference without simplifying. Squint heavily at your source photo; if half the tiny details disappear in your blur, but they are clearly rendered on your paper, you have over-copied.
- Dust smudging and falling pastel. Tap the top edge of your easel or drawing board; if a shower of coloured dust falls, you are applying too much pressure.
- Early layers pressed too hard leaving no tooth. Gently rub a finger across the problem spot; if the paper feels slippery and flat instead of rough, the tooth is crushed.
- Fur drawn as outline scribbles instead of directional masses. Squint at the animal drawing from an arm's length; if the body looks like an electric fuzzball rather than a solid, lit form, you have drawn individual hairs instead of clumps.
- Nose outlined instead of modelled with shadow shapes. Look at the nose in a mirror or in greyscale; check if the sides of the nose are formed by lines or by wide, soft shifts in value.
- Not checking work in a mirror or at a distance. Hold the work up to a flat mirror or invert the canvas upside down right now; any lean will jump out immediately.
- Subject has no focal point. Look away for five seconds, then glance quickly at your artwork: if your eyes dart around frantically rather than settling on one clear spot, you have no focal point.
- Trees drawn as lollipops: outline plus scribbled leaves. Squint at your tree drawing and ask if you could carve it out of a solid ball, or if it looks like a flat circle on a post.
- Animal legs drawn from memory with wrong joints. Trace the hind leg from hip to ground; verify whether the high rear joint is pointing backward (the true heel/hock) rather than forward.
- Colour palette fights: unplanned mix of many chromas. Take a photo of your painting and desaturate it halfway; if the composition suddenly becomes calmer and easier to read, your saturation is unmanaged.
- Composition cut off at awkward places. Hold your hands or two sheets of paper over the margins to test shifting the crop inward or outward by two centimetres.
- Dead eyes: no highlight, no eyelid shape. Check if your eye consists of a single solid black tone; if there is no distinct white or light highlight reflecting a light source, the eye will appear dead.
- Fixative darkening colours. Compare an unfixed corner swatch against a sprayed section to see the permanent darkening effect.
- Hard strokes never blended or layered. Hold the artwork at arm's length; if individual strokes dominate your eye before the overall form is seen, the edges are unintegrated.
- Landscape with no foreground, middle or background planes. Take a photo of your drawing on your phone and convert it to greyscale; check if the distant hills have the same value contrast as the nearest ground.
- Local colour only: ignoring reflected light and temperature. Examine the shadow edge of the object; if it is merely a darker, duller version of the light side, you have missed ambient bounce.
- Paper too smooth and clogged with pigment. Rub a finger lightly over the paper; if it feels slick like magazine paper rather than coarse like fine sandpaper, the tooth is clogged.
- Skin looks chalky from heavy white pastel. Take a photo of the portrait on your phone and convert it to greyscale; if the white areas bloom harshly without tonal transition, your highlight is too cold and opaque.
- Sky painted with one flat blue. Squint at your painting and compare the top edge of the sky to the horizon line; if they are the exact same value, the sky lacks atmospheric depth.
- Stopping too early because it looks fine in the phone photo. Step back three metres from the easel in normal room light without your device and see if the darkest darks still hold authority.
- Tangents: edges kissing awkwardly. Trace the silhouette outlines with your finger to spot any places where two different objects share an identical boundary line.
- Framing wrongly: cropped or overmatted. Place four scraps of white paper along the edges of your painting to simulate a mount window and see if any focal points get crowded.
- Shapes all similar in size. Squint at the artwork and group the elements into basic shapes to see if they all take up roughly equal area.
