That's a very good point.

Incorrect about the nipples. There is nothing wrong here about the bikini top placement. Nipples would normally be covered here. No one I have ever seen has nipples smack center in the middle of their breasts. The one thing I would say fix though, is the way they hang. They are so firm and it appears that gravity isn't effecting them at all. And with knockers that big, I am 100% positive they would droop instead of this image which depicts the upper body of a woman who would be standing but is really parallel with the ground (Horizontal).

I should probably delete this one.

Aside from what people said, is she layed down on the sand? If yes, you should add shadow over the sand, directly below her belly, left breast and left arm.

I like your style, but you need to study anatomy, specially women anatomy ;D

This cut at the neck composition is very confusing. Reminds me little bit of the photos in the movie Omen.

I think the breasts are a bit off. Well, so to say, I think you should move the bikini a bit more inwards.
Because currently she would have no nipples. I don't think the bikini would be over them the way it is now. So either give the poor girl nipples or change the bikini! ;)

I think you should have spent more time on the BG. the colours of the BG don't really fit each other, the sky is too dark compared with the foreground, the texture of the sand could be improved on and the edge of the sand/horizon of the sand is quite sloppy...

Besides that, it is a good piece... But I think you should really make the BG fit the quality of the character a bit more
