well this is a damn good picture of zero if I ever saw one! there is allot of detail in this for a spur of the moment picture and, the anatomy seems spot on. Lets not forget that perspective is coming into play here very nice! I Just love what you've done with this background, you made it look and "feel" real dusty and gritty very good very good indeed. Let not forget zero's awesome hair; you've very well in that area, it all flowy and dynamic, as it should be. the transparentsy of the recoil rods look right to me as well.
How the heck did I overlook this picture!? It's just too awesome. I say to make it even more epic, since the rods are essentially laser blades, it would suit to make them also be a light source. so having light reflecting off the armor from the rods will make this perfect.
