I re-did Shadow’s eyes - they were kinda meh, but I think they look much better now! To achieve this effect, I used a thin layer of glittery silver nail polish and followed by a thicker layer of red multi-surface acrylic paint. Because the paint was not sticking to the figure, but it the polish did, and the paint stuck to the polish just fine. (shrugs)
This is my first time painting a plastic figure, and, gotta say, my heart was in my mouth the whole time, especially since I was doing the eyes and it would have been really freaking noticeable if I’d messed up. As it is, the paint application could have been a touch smoother, but I’m pleased with the overall outcome.
