Hand Drawing

I was apprehensive about drawing the hand, I thought that it would be difficult since it has many details and it seems crucial to get the proportion correct. For a first try I am fairly happy with how the drawing turned out. I like the finger portion better - it seems blocky and unfinished, but I think it has more dimension and life-like qualities. The back of the hand portion, on the right side of the drawing, seems flat to me. I do not think I captured the bottom angle exactly right. In the future I would like to work on a view with the hand open.
