Welcome back, RR. The boobs are fine; it's a natural woman after all :p there are just things that look off when you go with the head profile 3/4 torso pose.
The real winner in this piece though is the logo. It's very scene for one, and all the formal pixel elements like dithering, shading, AA are all pushed very well.
I know you were just doodling around here, but I've seen some better pixels out of you man :p The palette on the figure and stars disagrees with me a little, probably because it's monochromatic and yet you're using it to give the impression of light, so really that's just me nitpicking. Not a whole lot of contrast in either and the dithering on the body kills the flesh texture. The opacity of the star trails makes it look less like motion and more like this girl's watching the miracle of conception.
