FFS, artist! That's not where the nipples are on boobs. LERN2ANATOMEE.
This is my biggest complaint about manga. About 75% of the artists don't know the actual anatomy of a woman, especially in the chest area. I've seen nipples stuck just about anywhere on a boob, boobs that start up by the collarbones, boobs don't flatten when the woman is lying on her back, cross-eyed boobs, unsupported boobs that somehow still have tight cleavage, and worst of all, boobs that overlap. 25 years ago, you might have had an excuse of not being to find reference material. These days? Not so much.
I've given up on face anatomy. Even in Western comics, face anatomy is just a bunch of symbols tossed together in an oval to denote an emotion. But given the riveting attention given to *oppai* in art and plot, you really need to get things in the right place. It's like you don't draw a character's arms coming out of their necks.
