Channel Art Feedback

[KantoGaming]

Hello! I'm just looking for some honest opinions on my YouTube banner and my thumbnails.

I've been trying to make my channel brighter and more colorful. I like my banner because it's my own art, but idk if other people like it.

I appreciate your honest opinions

Your art is pretty much perfect to be just by looking at it. It's nice and simple! I don't really have any comments on it.
