I don't think the image had to be so huge, but anyway. Her face looks kind of plastic. Like when someone goes ham on the airbrush post processing in photoshop. I think this is further accentuated by the pulled back hair style. It could just be a combination of distance from the subject and lighting. Something about the pants bugs me a bit. It almost seems like they are floating in front of her, like they were added as a second layer. I dunno.
Overall, nice composition and lighting. I do prefer the lighting in the first um, "pregnant candy stuffing"(?) shot. It's colder and matches the mood. The direction of the light casts some odd shadows on the background objects. I realize it was probably the best angle to get everything lit well. There might be a way to soften those shadows and make them less noticeable? But that's nitpicking really.
