I'm going to get a army belt, some clip packs and a gray dress that hangs from the back, from the belt. Like the arc troopers of of Star Wars Battlefront 1. And in the future make a custom jet-pack.
I used spray paint on the weathering. Yes m-16 you rifle, got it at goodwill one day. I used for the gauntlets pieces of wire and cut holes in the cardboard and stuck them through.
