Nice to see some Omori fanart especially of Mari (she's one of my favorites). I will say though that the anatomy here is a bit wonky especially the chest since its way bigger than most parts of her body, but at the same time I understand that you're a suggestive artist so I understand why you drew it big. Honestly if you can study some more anatomy, and get your colors down (don't worry I'm still working on how to use colors more effectively) you can make some really great stuff. And, I see this piece as possibly being a stepping stone for that. Keep up the good work!!
