First thing, Welcome!
The first image : The exposure looks great, I do like the processing. It looks a tad off balance, and I'd give her head a bit more headroom. Eyes tend to get drawn to tangency issues, where the subject comes very close to the edge of the frame but does not touch. You could also crop tighter and solve this as well. Overall a good image, a few little things and it's money!
Second image is wonderful! I love the processing, The model, the exposure. The only thing that bugs me is the little wrinkles below her shoulder... kinda distracting.
Great work and please keep sharing!
