Nicely done.. Realistic. I would say that couch looks very uncomfortable (Come to think of it, i think I saw one just like it being sold at the MOMA in San Francisco).. but I don't think that's what your concern was, considering you called it an interior lighting study. The lighting is very believable, not too flat but not too bold.

Love the Pop Art on the wall as well, nice addition. Did you use a reference room for this or did ya just make it as ya went?
