My guy, out of a 25 second video, only 5 of those seconds are the animation and the rest is just end credits.
Also, A.I background, straight up an AI generated image.
I understand backgrounds are a pain in the ass to draw, but If you're gonna use A.I, please either use it solely as a reference, trace over it or heavily edit/doctor it. Pretty much anything other than use the image as the way it came out.
