Silhouette

Original and nice setup – I like it – good work - John  

great concept, love the lighting.

I am not a fan of the processing.  The area where the couch meets the leg / bottom.  hmmm what happened there?  The arm, looks thin to start.

Look under the breast, fuzzy area. Not sure what that is.

Other than that, I love it, I like these shots but my focus was taken by the areas I mentioned rather than the great image I think it can be.

Thanks for your comment!

Well, the fuzziness is explained pretty easily by the lens used: an ancient Nikon Ai-S 1.4/35 at F/1.4. It has lots of spherical abberations and creates this effect wide open at sharp edges. That's one of the many reasons I love it, though ;).

As for the model (and the arm): she is very svelte and looks like she does. 

The problem at couch/bottom I see, that is probably contributed to the desaturation and contrast enhancement. That's the reason I uploaded the original photo (blue) after this one.
