I genuinely wanna explore that whole ass of his.~

I dont know this character but I think the shading is done pretty well as well as the color choices complement each other. The pressing of the skin on the pants is ok and tells me the picture is meant to be silly and exaggerated as that would probably be very uncomfortable to wear. I would know, I'm dummy thicc as well. Good work!
Just an fyi when I rate something I use the little tank man face to help guide what I should rate it, so it's a mixture of if I'm into the piece and then the quality of the piece itself.
