Amazing work. But I don't entirely agree with your Marine Pattern coloring on that default rifle. See, MARPAT was designed so that it resembled the rough boundaries found in a natural setting. Your woodland recolor, looked like a bunch of pixels thrown in random places, which would allow the enemy to immediately detect the weapon; and the Marine. A suggestion, group some of those blots up, and remove a lot of those yellow ones, as green and brown would mostly be dominant in a woodland setting, and a yellow dotted spot on the ground would either indicate mushrooms, or Marine.
