I really would've loved to see both hands, this one alone looks like some sort of freakish plant life :)

I do like it though, the glossy nailpolish is a good highlight.

I think this has great impact which could be emphasized by a better composition or tighter crop. Although I do like what appears to be hair coming into the frame on the right.

I like this. I think it's great the way the nails seem to really sit on top of the finger tips, rather than actually being part of the hand. Cropping more of the hair from the right might make the composition "neater" but then it is too claustrophobic - I'm sure you thought about that, too. I wish I could see the wrist that comes with that hand....
