I was curious about the underside of the armor that was always peeking out, and before I knew it, this one had been completely painted.
After much trial and error with the colors, I proceeded with the interpretation that the main body and the full-cloth parts are made of different materials, which means they should also be different colors.
Despite its small size, it's a cool machine with a lot of flashy details everywhere.
