I need some help with this before I shoot myself in the fucking face.

I have a tendency to get stuck on a lot of my drawings, and for some reason a lot of these are relatively simple poses like the one in the picture. It's like I can't draw if I don't have a more dramatic perspective to work with. It's like my brain refuses to understand form when I'm drawing something head on.

In this picture, I've also fucked the proportions beyond belief, and I don't really know why. I know the head is too small and the hips/legs too large, and it's just poorly drawn in general. I'm not used to drawing huge breasts, so I think that every time I enlarge the breasts, I redraw the body bigger to compensate, because the oversized breasts look odd to me.
I've put so much time into this pile of shit that should have been a quick and easy picture, and I just want to be done with it. A redline or any tips would be great.

The idea here is to have large breasts and an hourglass shape. I'm not going for chubby.
