You know, as much as a tiruly mpressive sight a large mass of gleaming white Stormtroopers look, I've always loved how some of the regular TK's in the films have slight scuffs and blemishes.
Your paintjob here maybe just a bit more than required pushing it almost into the realm of a Sandtrooper, but I bet you'd do a great ESB/ROTJ trooper.
Again, though great work!
