Greg, you had a really lovely model, but I think you missed the opportunity to do some really striking images.
Let's talk about the first image. It seems like your light is too high. There's lots of light on her forehead, but her eyes are somewhat shadowed. The tip of her nose is noticeably brighter than her cheeks. I think a slight repositioning of the light to a lower position or maybe a reflector to kick some light up from in front of her would have made this a killer image.
Image two has a couple of flaws. Somebody already mentioned the forehead wrinkles. But even if they were taken out, her overall expression just doesn't seem to match the pose.
I think if you had re-framed the shot to put her a bit lower in the frame and somewhat to image right it would have improved things. Yes, the arm would still be cropped, but unless you shoot this horizontally, it's going to happen. Did you try that?
But the main issue is the light, here the shadows show just how high the light is. If she had turned her face up and off camera, you would have gotten light spread evenly across her face. Closing her eyes and a slight parting of her lips would also add some extra emotional impact.
As it is, the light hitting her nose makes it stand out and grab your eye. Where you want people to look, her eyes, is somewhat shadowed and dull.
They are nice images, but they could have been dyn-o-mite images with a few changes. I don't know if you shot digital or film. If digital, you might have seen the problems by chimping. If you're using film, a Polaroid for test shots is pretty handy.
The lighting is soft and flattering, it'd be good for glamour, if it was redistributed a bit.
But that's all just my opinion, and whaddo I know...
Here's a shot somewhat similar to the second one...
