Well texture and material work, the explosion is a nice colour contrast and attention point for the viewer. Your design of the armor is also nice, especially the helment and bags at the side, and the weapon design for the trigger space.
Looks extremely awesome! Just one thing, in the background, the V-22 looking helicopters, why is there a crashed helicopter, but an airborne one that looks smaller than it as if it is far away, even though it is in front of the crashed helicopter? It kind of makes the perspective look confusing. Besides that, this is perfect.
