This whole design is made based off the toon smoke goal boost, I used black as its a very clean colour which most people would be happy with, I used the yuzo as they are a 5 point wheel which is like a star, the goal explosion matches the little stars on the boost and is black to match, I used Anodized yellow as its the initial colour you think of when you think of a star and its Anodized as they are bright/shiny

Nice design but maybe try black asterias?
