Interior scene night lighting

Hello!

This is my second Blender project, and Im sort of happy with the look.

The point of making this though, was to render the same scene in different types of light.
The daytime version looks alright I think, mostly because of the sun streaming in through the windows.

But when I try to make a dusk version everything looks fake and cartoonish.

Im not sure what is causing this. I swapped the HDR for a nighttime image.
I lit the spotlights over the windows using emission (not sure if this is the way to go)

Does anyone have some tips on how to make it look more photorealistic?

I attached a low quality render of the dusk scene (500 samples only).
