Her jaw line is... weird...
No clue what up with that blue collar thing. Maybe that's how it is in the comic, but if it's supposed to be to her back and not to her right side it should not be symmetrical like that.
The line coming off her left arm and under her rib shadow doesn't work. It's there for showing her shape, but it doesn't quite look right. It should be replace with a different line or perhaps we should see the back wall a little between her arm and torso... That doesn't seem right. I dunno.
crotch lines...this should be done with shading since that's a dress, or at least appears to be. The lines should be reduced or removed all together.
Her right boob is super squished...It should be slightly bigger and moved down a little more based on her other boob
Your shading on your colors are all over the place...I'm pretty sure you weren't trying as the shading on the face is pretty good, but there rest of her is all just quickly done it seems.
