This custom toy was based on the plain 6-inch scale Star Wars Snowtrooper, shown in the second row below. The base toy was completely white, and I had to take away the head and replace it with an Ironman head, before I started sculpting and painting the various parts.
The customized arm cannon on the left gauntlet is held via a magnet, as is the sniper rifle on the central backpack [which came with the toy, plain white].
Plus I added two axes from Marvel Legends Angela, and created the holsters for them on the sides of the backpack.
The shin-guards and boots were fully sculpted, along with their rugged white soles, the knee-pads, the skirt details, the mask, the chest armor, the shoulder-pads and gauntlets. He was spray-painted silver, before I added the greens and whites. Enjoy and share!
