Looks awesome no doubt but all he really need to to is prboably just get a body suit just to make him fill up that chest and back piece. other than that its really one of the best elite costumes i've seen.
its pretty good. only things wrong/needing work have already been said, bodysuit (or similar) to fill out the body, legs are a bit too humanoid, and the arms need a bit of work. other than that tho, WOW
