For now, here are some sketches to start! They're pretty much all figural. Oops.
(please forgive some of the out-of-focus in some of the sketches, I recently acquired a new scanner and I'm still fiddling with the settings. Unfortunately, it also blew out a lot of the subtler markmaking/shading in the sketches, hopefully I can figure out a way to have that not happen.)
Sketches mainly from observation (some I was studying leonardo's drawings, some looking at some photos I had taken of sculptures, one from a random pose generator on posemaniacs):
Sketches done without references/not from observation (mostly character-concept based):
Crit away! I'll be posting sketches specifically from today later.
