Very interesting, reminds me somewhat of the one from Black & White.
The shading on the second leader's hat looks odd, so you might want to work on that, and as for the 3rd... You may want to consider restarting from scratch, it looks very bad. Not meaning to insult you, just a couple of things you might want to work on.
thank you for the advice. I'll work on the mugshots. and as for falkner he's just a placeholder for now until i get the chance to make the mugshot of the first gym leader.
