The color scheme you chose for this picture was a good choice; it's not to light nor too dark for the theme of this work. You definitely put the right amount of detail into this piece as well (being folds in clothing, seams of pants, etc.) The background to this piece is not just one solid square, it's more of a human-oriented emphasized background that I find to be quick, easy, and a good idea. Though in your description, you say you didn't really focus on anatomy as much as shape and whatnot, I believe you still did well on the anatomy. There's not much I can say is bad about this picture at all, really. I think you definitely put your heart into this work and it looks great.
