I like the fact that you used ai to make the art. Btw which ai did you use?

Using A.I speedup the process in a Game jam but of course working with real artists is better. I used https://www.bing.com/create which is for not commercial products. You need after to edit the output . I used paint.net and Krita that saves in PSD format ( which is great for multi-layer) and Unity imports.
