Starting with the head. It's the front half of a target lock up front, burst cannon disc around the bottom, little cone shaped fusion blaster sprue piece on the back of the head, Kroot rifle blades on the side of the head for the "tusks".
The shoulders are the dreadnoght torso side plates cut down, the left longer than the right for the Fire warrior look. The right torso is the dreadnought light assembly from below the torso (came with the torso set....it's kinda like a turret ring so to speak.) and below that is a flamer canister. The left side is bit of the 'fish deck plate combined with a flamer canister below it. Down the center is a crisis shoulder cut down a little with two stealth shoulders below that. The middle one is cut, the lower is full sized. The thighs are covers with the dreadnought engine cowlings cut down (they have the exhaust stackes on them originally), and the shins have cut down stealth shoulder pads covering them. The back had the lower halfs of the 'fish antenna attached on each side of the center engine intake. attached to those are two fusion blaster canisters. Thanks for all the c & c everyone. I'll post pics when it's finished. And yes the big flat areas of shoulder are getting decorations for sure.
