It looks really cool. Well-done. The glass panels look like a glass, moreso than a metal. There’s a tutorial on youtube on how to create an opaque glass material, which is quite simple and looks great. I don’t know if I have the link to it anymore, but try a search. The idea to use dual normal w/ clear coat was based on how that’s used to create something like an overlay for vehicles such as sports cars and boats. It’s basically 2 materials in one, non-technically speaking, with one a thinner layer over a base texture / material. I thought a small panel mesh inside the respective parts on the robot could be the base texture, and the clear coat would’ve become the see-through glass with a low level of opacity, and perhaps a moderate amount of refraction or visible light bouncing effect.
Some of the best robot type character models I’ve seen are in the Armored Core games, and most of those are on older generation consoles. Even the robots from certain PS4 games don’t look as cool as the ACs in the Armored Core series (of From Software creation).
