Wayyyyyy back when I started, Jin Saotome made his Sentinel which floored me. I started sculpting onto the head of a mecha hulk about ten years ago then gave up on the legs. Fast forward to last year when the Hulkbuster baf got released and I knew I had to swap the recipe up. Sprayed him chrome and used blue tamiya ink and purple. Muddied him up with black ink. The effect is a ping pong ball covered in hot glue, wires and yellow ink. The mini sentinels are Marvel Universe Stealth Iron Man with retooled heads and chest details.
