I'm curious as to the "crack" by the guy's left collar bone. If you can, I suggest that you remove that little bit. I don't think there is anybody here that doesn't like color, but I like colors to be clean yet still punches you in the face when you see it (figuratively speaking of course ). The shade of green is a bit bland, it doesn't have as much flavor as I like to see in colors. I think it does work well, relative to the ambience youre trying to create and the feeling youre trying to send. I'll leave the typography alone (although, I dislike pixel fonts on most occasions, this being one of them). It'd be nice if you could surround the render just a little more, still leaving his collar bone and up moderately clean, especially the face (its requisite to have visibility of the eyes). When I say surround it a little more, don't just brush over it, make sure that it looks almost like the guy is running through a cloud of smoke/fog/mist or something like that. You don't need to smooth it out a ton, but it'd look better if the section in the top right (where its a dark green) was a little smoother and less rough. Don't make the brushing fade of super quickly on the left, make it a little more gradual, but you have it pretty well done now. That's about it for this one. Make some large work from scratch, I wanna see that
