Prtetty cool. Is the yellow dude supposed to be dead/slumping against the wall? If so, then it looks fine, to me. However, it looks like much of the picture is still a wip, such as the green guy's hand and sword handle. The bricks on the far wall look as if they were scribbled on as an afterthought, just to not look empty. Actually, ut looks like that in alot of places. Those crystals on the wall look really wierd, too...I dunno why, though, as I don't see crystals very often. It looks to me like the guy's lower leg is a bit too short. You've got a buncha seemingly random pixels in the green areas. Jagged lines seem to invade just about every part of this picture.
All that aside, this pic is really cool. You might want to consider tweaking the pallette a bit to add some atmosphere, but it's still cool.
