just sketch

Sherlck Holmes & Dr.Watson from 2009 film--I've become a big fangirl of this movie>w<

I know this pic is lame, but I have to draw some sketchs of these two guys before I can draw something more than that. I didn't post some earlier sketchs beucase they are even worse I think this one is not bad compare to the ealier ones, but they are still pretty bad...hm.

Law is definitely hard to draw....

I believe more sketchs are coming, but I wanna hear some advice first-anything will be good. I'd really appreciate if you can tell me is there anything I can improve. This is the best sketch I can com up with so far-and I really want to know what I missed.

Thanks!
