Welcome in from the shadows Bob! These are actually not too bad. Exposure is good and composition is okay. Lighting wise I like the horizontal image better. The vertical one looks like direct flash on camera. If you can manage it you need to find a way to get the flash off of the camera. The lighting on the horizontal is much softer. The crop on the horizontal image works okay as is, but I think I would have prefered a little bit looser crop showing just a little more of the model.
Here is one of mine.
