My interpretation of Ultraman

I needed to practice some metallic shading, and I haven't drawn any Ultraman characters yet, so I drew Ultraman.

I read that the red parts of Ultraman originally were meant to be organic, while the silver parts were metal, so I went along with that Idea. For some reason I had the idea of the red parts to be pure muscle, so that happened. And those lines on his muscles are supposed to be texture.
