I like your model, the use of shade, and simple backgrounds. I have a few suggestions to "fine tune" your images (my opinions...yours may vary).
Flat on poses do not do her justice. I try to have the model pose at a side or 3/4's pose and try to curve the figure. Also, as part of your PS regimen, try to eliminate ‚Äúcolor cast‚Ä? with you color tools. I find almost all images are biased with digital.
One small item on above, if you are posting 3 images it is nice to try to make them all with the same white balance.
Finally, the use of props adds to the interest of most glamour images. I feel they bring out the creativity in the model, give her something to use and in some cases helps to relax your model. Be sure it fits the scene though.
