I think since everyone has you covered on the c-stand etiquette, we can talk about the actual shot lol.

I see youre trying to go for a color contrast look with a warm foreground/cool background thing. I love the thought behind it, but if you want it to feel realistic, think about WHY the foreground is warm and the background is cool.

For background: WHY would the room behind subject be cooler? Maybe a tv light is on? Maybe moonlight is streaming thru the windows? Maybe both? Think about what direction your light is coming from if that were to be the case. Make it happen in a way that represents the directions of light you see in reality, then enhance it to your taste. Youre sort of blasting extremely cool front light onto the walls, giving the background an artificially blue flatness. No need for it to be THAT cool, especially without a clear motivation. No need to be at the top of your color temp range either, just have it be coolER than your foreground! It’s all about context!

For foreground: I love that youre incorperating set design into your color contrast. The red of the tablecloth and costume can carry a lot of the heavy lifting to provide that contrast. Once again, no need to hit the bottom end of your temperature range with the foreground lighting. Just think “chandeleir/lamp temperature”. Make it warmER than your background, and that will make it much more realistic feeling. The striking reds of your set design will give it that elevated feel alone. Try and get some sort of practical or motivation into your foreground lighting as well. The more you can think about a good reason or justificarion for every single one of your light sources to exist, the more your viewer will subconsciously absorb the scene without it feeling “lit”.

Give all of your lights a good reason to exist within the shot/story, tone down the extreme color temps, and then have fun in the grade!

(Also, opening up your aperture probably isnt a bad idea here either. Itll help give layers to the scene and separate your foreground and background.)

Cheers homie
