Despite using reference and taking my time with this piece...I don't know its because i've been looking at it so long, but it dosent look right? Or alive? Seeing other people's artwork in manga or comic styles, and comparing this to that, it feels like i'm still missing something that I can't seem to achieve. Any critique on the piece itself? Or even advice?
