Just a small critique I've been noticing. In the last few pictures the woman's always looked the same, facially speaking; I don't know if this was on purpose of an accident but it might be something to take note of. I know I see alot of other artists like us who love doing comic book art, but who just use the same face over and over on all there characters, it's a great trait to have if you're always drawing the same character, not so great if the characters are different each time.
If it has been an unintentional trait I'd suggest getting say, a people or enterainment magazine and drawing different actresses out of it.
That's what I did to break my 'same face' habit.
