I love the base black color with the red in the back round really gives this photo a feel to it, it helps you stand out more in the photo but the red is bright enough that you still notice it. I think the lighting is just a bit low of your body, if you had the lighting up higher you would've had more of a shadow on the lower part of your body and in my opinion it would of added more of an affect to the photo. Also i think you have stretched out just a bit too much for your pose, don't get me wrong the pose is beautiful and stretching out isn't a bad thing but if you had not stretched your stomach out that little bit too much you could of had more of a curve to you waist to your lower rib cage and boobs. all in all i think this photo is beautiful i wouldn't have thought of anything better but changing the height of the light so it comes down your boobs, face and outa rib cage making a shadow that would fade down to your legs.
Congratulations. Several other DA photographers have extensive photos of Liz, but they fall short of 'art photography.' Liz is lovely, and I'm pleased to see that you've figured out the "Riddle of Liz." Wonderful photos. I hope you continue to work with her.
