Why does my drawing look flat?

A flat drawing is usually accurate. That is what makes it so frustrating — the shapes are right, the proportions are right, and it still reads like a diagram rather than an object. The problem is that you have drawn what things are rather than what light is doing to them, and there are only four ways that goes wrong. Work through them in order.

Step by step

1. Check the value range first, in black and white.Photograph the drawing on your phone and convert it to greyscale. Now look at the darkest point. In most beginner drawings it is somewhere around a mid grey, which means every tone in the picture is squeezed into the middle of the scale. Nothing can look solid if nothing is dark.
2. Push the darks much further than feels right.The shadow side of a sunlit object is far darker relative to the lit side than it looks, because your eye adapts as it moves. Take the deepest shadow to near black with a soft grade, 6B or 8B, and build it in layers rather than pressing hard once.
3. Keep one genuine paper white.Contrast is a relationship. A near-black shadow only reads as dark if there is untouched paper somewhere for it to be compared against. If you have shaded the whole sheet, lift a highlight back out with a putty rubber.
4. Vary the line, and lose it where the form turns.An unbroken outline of even weight all the way round an object makes it read as a cut-out shape. Press harder where the form is closest to you and in the shadow, and let the line fade or disappear entirely where a lit edge meets a light background. Losing edges is what makes an object sit in space rather than on the paper.
5. Draw the cast shadow, and anchor it to the object.The shadow an object throws is what glues it to the surface it stands on. It is darkest and hardest-edged where it touches the object, and it lightens and softens as it travels away. A drawing with no cast shadow floats.
6. Overlap things deliberately.Overlap is the strongest depth cue there is, and it costs nothing. Arrange the subject so one object clearly passes in front of another. A row of items in a line with gaps between them will look flat no matter how well each one is shaded.
7. Change the sharpness with distance.Whatever is nearest you gets the crispest edges and the most detail. Things further back get softer edges, less contrast between their own lights and darks, and less texture. Drawing everything with equal attention flattens a picture faster than almost anything else.
8. Check the light is coming from one place.Beginners often shade each object from a different direction, because each one is drawn separately in a separate sitting. Pick a light direction, mark an arrow at the corner of the page, and shade everything to that arrow.

Tips

• Squint at both the subject and the drawing. Squinting destroys detail and leaves only the big value masses, which is exactly the information you are missing.
• Hold the drawing next to the subject and compare the darkest dark in each. Do not compare shapes — compare tones.
• A drawing seen small shows its value structure instantly. Step back three metres, or look at the phone photo at thumbnail size.

Common mistakes

• Adding more detail to fix flatness — Detail is a surface property and flatness is a structural one. More texture on a form that has no value range makes the picture busier and no more solid.
• Shading everything to the same mid grey — It is the safe move, because a mid grey is hard to get wrong and easy to erase. It also guarantees the drawing has no contrast anywhere.
• Outlining everything at the end to tidy it up — A uniform outline flattens the form you just spent an hour building. If you want to sharpen the drawing, sharpen the darks instead.
