IMHO, these are much improved in terms of camera angle and lighting...more dramatic, without being overly so. The light coming through the window now projects Vicky's shadow onto the back wall reinforcing her isolation (though I would think the same light would cause a small shadow to be cast by the picture frame also). The new placement of the couch is a bit odd from a realism perspective, though I am assuming this was done to help achieve the light and shadow that I do like. Also, from this angle we now see a bit more of the floor, and the flat black seems unusual. But those things are minor nits in comparison to the improvement these renders represent. Finally, this may be solely my personal taste, or it may be that you have yet to focus on this aspect, but the expressions on the models' faces are very understated, particularly Victor's. When I look at these renders, I'm not sure whether he's sad, mad, or reflective. I mention this because I know your portrait work is very expressive (again, without overdoing it). Again, these things may just be me, but maybe some will provide a spark for you.
