Anatomy and proportions are wrong (mainly head and arms). Breasts are way too big and kind of strange actually. A lot of excercise ahead.
The color you used to AA the black outline lacks contrast to actually work. Maybe it is easier to outline the figure with black first, then apply AA to smoothen jaggies that will appear.
Check her proportions, arms are too short.
What is the dark spot on the top of her breasts? It looks too deep to be the flat area between the breasts.
Is the character naked, or are they wearing something that pushes the breasts together? The breasts are positioned as if the character is wearing something quite tight, but nothing is drawn.
Mmmmh.
I get the pure art: the small arms are supposed to make the ( )( ) stand out right?
Thanks for so much useful feedback, guys. That helps a lot. Much appreciated.
