Need feedback on my first substance painter study: worn out pokeball

LeoPolichuth

This is my first attempt to paint textures with Substance Painter

I don't really like the red part of the pokeball, I'm not sure why, also in general I have to understand better how some materials are worn out over time. I need some feedback on what I could improve with the materials.
