Very cool. Mind explaining a bit on the darker metal? I really dig it. Looks like you did the dark underbase and then airbrushed the metalic on, but the only metalics I have tried just clog up the airbrush so I've had to hand brush it on, but can't get fades that way.
I think it will have the Scott Marshal open mouth P1 with animatronic rig, not sure as I'm building this for someone else. The armor is pretty easy, just base coat and I use a terry towel to wipe on the bronze and silver paints. Today I weathered the deerskin for the front and backside. The skin was too dark, so I placed into a bucket with bleach and brown dye, this is how it looked the next day.
