he overlaid scales are a holographic foil spandex that has a dimensional illusion. Very reflective of light. The arm fins are unfinished pending any light strips the lighting designer might want to contribute. We could make hood of same holographic material with lighted fin down back of it, Mohawk-style, or we could use neon green spiky wigs with or without fiber optic hair lights and add leg fins. I like arm fins and either wigs or hoods but not leg fins, personally.
