Not really a custom, but I put this build together from pics of the Henshin wave. As an experiment, I hit the final build with Monster Kolor gloss to shine it up, and now t looks like cut glass. Awesome.
It’s a complex build, but having a fully articulated Glyos figure is great.
Prometheus Rising Studios 
how much?
This guy’s not for sale, since he’s really just stock parts, but if you had a clear build I’d gloss it up for you.
