Wow... I really like it!
Only thing I can see: Scale the fingers a bit. The middle finger should be a bit longer than the two next to it, and the little (pinkie?) finger should be the smallest... at least that's what my hand looks like ...
other than that: Very low poly, and it looks great! I really wanna see it skinned
