I do agree drawing hands (and oddly enough shoes) is my biggest weakness. I have been known to get lazy and draw hands in any position to hide them.
I guess I could just draw creepy skeleton hands like Naoko!
Also, I think you should place all of your fan art into one post so we can see it in one place. It's less likely to get lost in the mix that way.
I think we should all make threads sharing our fan art.
