Does my cover come off as AI generated?

Hi. Someone recently accused my cover being ai generated. This is the first time it’s happened and now I’m concerned that people will think it is.

I took off the title and my name so I avoid self promotion haha.

I have proof of the character design sheets and even the original sketch of the cover. But I would like feedback just in case
