Photo wise, I don't think there's much you could do better. The details seem to have "run" a bit on the lets, like what one would get when the paint on a wall runs underneath some masking tape. And overall, the brush control looks to need some practice.
One big problem is with the guts. They're monochromatic. It would do well to have some differing colors that would help separate all the parts.
I think the damage on the toes is spot on and very good.
