Lighting night interior with few ressources

Hello everyone and thank you team Deakins for this very valuable place that this forum is.

David here, back at studying cinematography, and currently far from home for a few months. All I could bring is my Pyxis6k, 24 and 50 mil lenses, tripod, a 60w mini cob and a pair of reflectors/diffusers. Where I live I have 4 practical lamps, and two mirrors. As for the furniture, a black table, black chairs, black bookshelf, a black sofa and a shiny black coffee table. Walls are white though.

I do that on myself, alone on my spare time so I though it would be a good exercise to shot a simple short scene with 2-3 different shot values and reiterate to two three times to try and test variation in the settings.

I made 2 iterations with some happy results and some unsatisfying ones. Since I have no crew to exchange with and get some fresh ideas and perspectives, would you mind sharing some knowledge, advices or ideas about lighting for full black furniture set with a few lighting ressources.

Also, might be a trivial question, in that settings, night scene with 2700k practicals and one unknown kelvin practical, how would you set the WB of your camera, round up to 3200 or line up with 2700 ?

Looking forward reading your thoughts.
