Question here: Is it too dark for a night scene?
the only light that would come through (in "reality") is the city-light from a window on the right.
i have added a light in the room, too. - so there are 2 light sources.
4k render to about 50% (if i remember correctly) and downsampling to 1080p.
I believe, that it is very much in the eye of the beholder. Some want's to see all, and some like it dark, were focus is automatically drawn towards the important parts of the image. The parts that you, as a storyteller, want's to show off.
So, there are varied responses to that questions.
In my opinion, it is too bright, from the waist up. But like I said, thi sis just my opinion.
I'll throw in one of my own: Only light is "distant light".
Like I said, i like more contrast in certain images, when it comes down to light and dark.
