Not actually a comment on lighting, but about chauna on couch. I see he must be rigged, for him to be sitting on the couch.
Something i have done for a long time now, with any character, is to make a pose, (2 frame sequence, double keyed), of the hands, with fingers slightley curved.
It makes a huge difference in any image, when the fingers are not so straight.
Just a thought.
Otherwise, looking good.
