Great use of G.I. Joe parts Kit Fisto! Normally I'm not a big fan of G.I. Joe hips/legs on Star Wars customs, but for some reason I don't really notice the different articulation here. Maybe it's the great paint job/weathering.
That helmet is kickass too, it's different enough so that it obviously isn't a Fett repaint, but it still screams "Mandalorian!" to me. Great work!
