Edit with added contrast and sharpening
Glasses repaired B and W copy
Glasses repaired-reflection left in due to lack of clone material in top of lenses
Added to recover highlights-Glasses retouched
I left the original for comparison. If you take all of the texture away in the background it appears you were cut out and placed on the background
Another option with darker and smoother background
Not a major edit. Let me know if this works for you?
