I've always loved to draw hands, even though it's usually really tricky, and they nearly always look really silly until you're a fair way through.
I'll get plenly of practise drawing hands in the pieces I'm working on now though. Hands in nearly every one. For the moment they're all female's hands, so at least I can model them on my own.
When a guy's hands are required, I call Steve in to model, and he gets the joy of not being allowed to move for a very long time instead.
