Got through the shadow section. Kinda. Now onto the hashing.
My hashing is woeful. I have no idea how people manage to make lines so uniform. Heck, I've got no idea how animators/ cartoonists manage to draw similar figures all the time so you know what you're looking at. My hand-eye coordination must be dreadful. Still. Perseverance.
A friend sent a message to me giving me some encouraging words around negative space and its use. I agree with his recommendations but... I think I need more thinking around organising/ construction-lines/ anchor-points to try and get things aligned.
