Human Models- Work in Progress

Lately, I've been trying to build up my library for topics to draw and render. Since my hard-drive has quite a few dinosaurs on it, I figured that I should start working on human models.
Now, it may or may not be very clear from that guy's dead facial expression or lack of clothing, but I'm not quite finished with these models yet. If you guys have any comments, let us know below!

Rendered in Blender.
