Not to nitpick your crop, Traveler, but they feel a little unbalanced to me. Probably because the close eye is almost right in the middle of the image.
I just tried cropping the first one and couldn't find one I really liked. I think the combination of her leaning back and the crop coming up as far as it does on the bottom makes it difficult. I think her pose combines better with a horizontal, but with more of her in the image. If I were to crop this one, it would end up really tight, but even when I do, I can still see the slouch.
On the second one, I do agree that the large area of bare flesh pulls my eye (bright areas do that), but again, I can't really find a good crop that I like, so I'd probably leave that one. Changing the lighting up or the pose would help with that if you were to reshoot.
