Pretty cool.
I'm not the biggest fan of the style, but I always keep the bias out of my reviews. It's really simple, but done very well. I love the stance that he's in. It shows that he has just dodged something or jumped from a far distance. The smile on his face makes me think that he did it to avoid an attack and is showing a confident/smug attitude. The stance shows that he had to give way to a far jump, but that he's positioning himself to be on the move yet again.
I can see this being used in a flash before. It's the type of style that does great in flash submissions. The glow around him is really affective. Looks great. The only thing that I can really comment about is the lack of a background. I know that it was to focus on the character, but the proper placing in a good setting could bring this picture to a new level.
