I'm going to admit two things.

A. I haven't drawn a back in years. I used reference for this. I'm hoping to get back anatomy down a bit more sometime.

B. I've come up with something I'm going to call Darkhart disease. Basically, any of my characters who have the last name Darkhart are, for some reason, prone to being drawn. Frequently. Usually several times in a row.

I'm hoping to explain this with science.

EDIT: Oh. Yes. I was too lazy to draw his hand or lower legs.
