thoughts on the one on the right? i think that one turned out the best. i emphasised the back which is where the action is, i established relationships between the lines, i drew in the direction of growth, so even if it is anatomically incorrect it works.
i didnt do any of that in the middle one and left one. in the left one i did whatever, just copied from observation. the middle one i stacked forms on top of each other (i erased the overlapping lines).
and during those i remembered i should use the lessons learned previously in the book so i applied them for the right one.
