Life-size drawing of the human skeleton.

This is a life-size drawing of the human skeleton, drawn on A0 paper. It's based on a real specimen rather than a model, which is why small deviations and asymmetries show up that a textbook illustration wouldn't have.

Getting the proportions right meant a lot of measuring. The biggest challenge was perspective: standing close enough to see detail distorts whatever's nearest to you, so most of this was drawn from a distance, stepping back again and again to keep the whole figure accurate.

The cartilage was built up with a hardening plastic. Giving it a light blue, slightly see-through colour was an artistic choice rather than an anatomically literal one, a way to let it read clearly against the bone.

The graphite drawing was done in sections, then scanned and assembled digitally. Colour was added afterward in Photoshop, layered over the graphite rather than replacing it, so the original pencil texture stays visible underneath.
