This is very nice. It is very soft, but I think that is supposed to be okay for this type of photo. The cropping could be called a bit "tight", but I like it.
This one looks a bit underexposed. I can't quite tell, but the white balance may be off as well. Here eyes are a bit dark too, I think some more lighting on her face may have helped.
Really like it, the softness of the photo is great. I actually quite like the crop myself, but im no expert (yet)
Definate improvement. Proper exposure, soft, good lighting, good angle. I'd just work on the crop. At least get the rest of her forehead and some hair.
