It's not a matter of right and wrong as much as it is style and technique.
Here's a question for you -- why did you tilt the camera in the first image? It looks a little odd -- and makes her right earring hang funny and her right arm gets chopped off at the elbow. Yikes! I hate seeing models with no arms!
The second image -- well, let me ask if you have an image of her, sitting on that bench, taken from just off center, where she's giving you a bit of profile. Probably taken from a low angle? That's what I would have shot -- 1) it's a more flattering pose, 2) it's easier on the viewer to sort out the angle and 3) you might not have lost her dark, non-reflective vest in the background. If you're going to lay her down like that you really need to stretch her out. It may feel funny to her and look funny while you're doing it -- but on camera it should be more flattering and easier to look at.
Some of the best images are just straight ahead, simple poses that respect the light and work with what the model has. I think I'd use that to describe lots of what JT Smith shoots. And JT's stuff is ALWAYS right on.
Something simple and straightforward...
