Atlas - Acrylic Picture

Well, here is a try at anatomy with acrylic paint on canvas. I didn't really use a reference photo here, just browsing through hundreds of pictures until I got a somewhat decent grasp on the anatomy. I've still got a long way to go, obviously, but I think I did okay, I particularly like how the left hand came out.
The title "Atlas" is a reference to the mythological titan who held the world up on his back.

Anyway, I'd love to know what you think! Questions, comments, and constructive criticism are welcomed!
