I'm attempting to go for a video gamey look, with vivid colors. I don't know how better to describe it, but this has been a challenge. I'm using the Holosmith Sword, Super Aventure Box Pistol and Scarlet's Rainbow. Recognizing that "video gamey" is too vague, I suppose I could just say I want to go for a more Super Adventure Box aesthetic. I initially tried to play with a megaman cosplay, but I couldn't really get it to work, so I dropped it. Alternatively, I suppose I could describe it as neon 80's or a Tron look as my initial idea. Ultimately I just couldn't figure it out.

Any advice on how to make this look better? Either just general tips to improve the visual attractiveness or any advice to fit better the theme.
