This is my upsized Masterpiece Prime. Everything except the head, hands and joints are scratch built from sheet styrene. He has full articulation- head, shoulders, bicep, hands, waist, hips, knees and feet.
He took one week to put together, and another two-three to paint and detail. His gun attaches to his back with magnets.
All in all I'm really very happy. The only thing I'd change would be the height. At 1:18th he's 36 feet tall. And at 1:12th he's 24 feet tall-- which is where I'd like him to be.
