It's a good pencil sketch...
...It's a pretty good pencil sketch. Personality and Character do come out in the drawing, I feel like you could push it a bit more, with exception of the face seems a bit sketchy.
...I also get the underlying first impression of "Western"...could be your color choice as it kind of resembles a wanted poster theme, and the dress is both time appropriate and character appropriate, like he's a card dealer.
...I know it would take away the dramatic effect of his white eye's which is what you're obviously going for, but he's gotta see...pupils?
...All in all good drawing, but challenge yourself to push it further and you'll find that you become better at a faster rate...settling for "good enough" won't get you any better :)
hope that was helpful
