Is it just me, or is there some odd processing halo where the back of the guy's sweater passes over the vertical column on the left side of the frame?
Highlights on her blouse are blown out, but that could just be small image size/bad JPEG compression. Check the original if you haven't already.
Without her navel in view, the tummy is sort of disoriented bare skin, and quite a lot of it.
This does not strike me as very flattering to her, but maybe it's the best that can be done. She looks pretty enormous here, but maybe she just plain is, and maybe even that's what she wants the pictures to show. The fact that her slacks(?) are coming out flat black isn't helping here, I think, but again that could just be small file/bad JPEGishness.
The flyaway hair is not so good. Her hair looks a little to "done" for this to be a "natural breezy" look, so it just looks like an error.
Her expression isn't all that. Isn't she supposed to look more radiantly joyful? He's pretty good. Perhaps later in the session, after she loosened up, she might have looked less threatened by the camera.
The good parts: She looks quite lovely. Good makeup and styling. The necklace might have been draped a little better, but is basically a good idea. The colors look good. Focus and framing are good. Given that the blacks and whites are equally blocked up, I'd say exposure was in the ballpark. Light's not bad (was this shot overcast, and then warmed up in post?).
