Now, don't go crazy on me. I'm a friend, but that doesn't mean I'm giving you 10's because you're my friend.
I really like the hand. But it needs to be a bit straighten out. (To the left.) Based on the shadows, you should work a bit on the edges and the corners on the body. A great way to do this is to make a circle to the left (or right, based on which side you want the shadows on.) then make a small line to every place where you want a shadow to start and end. It's hard to explain but if you get it, it will help you alot. The circle is the place of the light that beams down. so try to place shadows where the light can't reach them. And a tip is to take things calm and don't rush it. The time doesn't matter, It's the quality that does.
And NGGP, enjoy flaging this review. I don't care. That just makes you more of a kid then I.
