See what I have to start with? Here's how far I've gotten and I'm not too happy with it. Oh, sorry about the pretty face thing..
I layered up a couple layers of inverse illuminance copies to build density in the dark areas. Stacked a multiply layer (which makes it quite dark) and masked out the face area that I wanted to shine through. I touched up with cloning and minimized the double flares in the eyeglasses. I cloned some background from the left to the right and added some blur. Of course I added some pure black space at the bottom just to let me frame the face appropriately.
The face itself is ok, but I was at a loss on the background and bottom areas. Does it look like he's being engulfed by some black fog? I thought of duplicating the RH sofa on the left so I could balance the sides and include that space, but would have a big challenge getting the lighting to look right. Suggestions?
