You really need to ease up on the Sharpening Tool. [img]/ubbthreads/images/graemlins/wink.gif[/img] I personally like images that are a litle soft but when I sharpen an image I usually only sharpen the eyes and lips.
The reflections from your lights on the latex outfit are quite a distraction. The eyes go immediately to the brightest area of the image, which in the case of #1 is the highlights on her outfit.
You might want to try bumping up the contrast in #2 as the gray tones are muted and muddy.
Keep shooting and try to get your images in the camera insted of using photoshop. I like your concepts here and would like to see more. You mihgt also want to try and put these two up on the post production forum in their original form and see what the phjotoshop guru's can do.
