Very good collection of hands :}
good work it's looking good!
Hands are hard to draw! Anyway nice job on them!
Yeah, they are quite complicated thingies, especially since they can move and change in volume so much. If you see the arrow in the lower right corner, I have marked that I started drawing in the bottom row from right to left and then moved up and drew right to left. And its quite cool to see the hands improve as it goes along!
