Man..hands are super tough sometimes. It's one of those things that you can see how they work even in the subtle details..but actually drawing a set of hands takes lots of time and practice.
This is a sketch that I worked on for a Daily Sketch Challenge over at Deviant Art..but the hand was effed up. I did it a couple of times over to try and get it right. I think I like this final result..but yeah more practice on hands needed.
