After the cat I just knew that chibi was a great medium for you – and so far it looks like it is working out. Great start to the little blighter.
Hands, ugh. I had a devil of a time with them. If you are going to do a hand holding a staff/spoon/axe/whatever, it is worth twisting some wire around the object to stop the hand moving around. I didn't do that at first and every time I touched him the staff would carve a bigger and bigger hole in the hand, and wobble about everywhere.
As for sculpting an open hand... well, I don't recommend it!
