Second pregnant lady I have seen in this challenge. I liked the other one over yours mainly because of the white top. Here it just looks blown with no tonal variation.
The white shirt is far too harsh for the somewhat muted tones in the rest of the image. The tonal range of the image seems to be missing both whites and blacks aside from the overexposure on the shirt itself. Even adding contrast with a curves layer would still leave the white shirt there to grab my eye and prevent it from exploring the entirety of the frame. Aside from the shirt, here is the edit I would have offered to offer more depth to the viwer.
Her pose also seems a bit uncomfortable. Placing that left arm behind her almost makes her look like an amputee or that she is struggling just to sit in that position...not that being 9 months pregnant isn't a struggle within itself. I like the belly and the content look you captured on her face. I think with a different shirt color and a slight pose adjustment your score would grow considerably. This one gets a 5 from me.
