Initial Character Faces

I got bored of drawing featureless figures, so playing with ideas for my game's protagonist. All I know right now is that he should be an old(ish) guy from the 1800s, with an attitude and ever so slightly violent past.

What do you think? I'm gonna draw a load more, so if you think of a mix-and-match that makes sense or have some awesome source images then let me know :)
