I like it! The texture rather charms me, with that sort of cartoonish look. You also seem to have a good edge flow going on there (Not sure since I can't see the palm of the hand, but from what I can see it looks pretty good) but the tops of the fingers are all too flat, which I'm sure you're aware of. I'd say repositioning the edges on the fingers a bit so that there are three on the top which will give you a bit of a smoother look.
Also try to smooth all the normals of the hand, as that might also help the flatness of those fingers quite a bit.
EDIT: Could you provide some shots with the hand non-curled as I just noticed the hand looks a bit thin/flat in general, but the position of it really makes it hard to tell.
