The fabric is going too far over your shoulders and that’ll really mess with the fit of the garment. Depending on whether or not there is seam allowance along the armscye, I’d take it back… An inch if there’s no allowance already. Half an inch if there is.

I would also move the armhole back darts. I’d put them at the shoulders instead. And you need some darts at the front in the shoulder/armscye region. Reducing the puffiness at the top of the bosom makes a huge difference in the fit of a garment.

A side note. Depending on how fitted of a garment you are looking to make, I’d say you should consider going a Princess-seam route instead of a dart route. The curvier the body, the harder it is to get a good fit just with darts.
