need critiques

[shinji-eva01]

Just started a life drawing class but first day there was no model. Wednesday will be our first model. So for now I've been drawing my hand or figures from a nude figure book. I need help on what I should focus on during class.http://davis.chung.home.attbi.com/hand.jpg http://davis.chung.home.attbi.com/figure.jpg
Thanks.
