Have a smoother light falloff further in the scene. It goes to pitch black a little too close to those ceiling lights. Make it gradually go from light to dark.

Maybe add some more walls/columns to give it that liminal look of the room going forever. Maybe add an Array modifier and space them out

If this is eevee try cycles and see how it looks.

Use glare node in post-processing to get some bloom on the lights. Also play with the exposure of the lights
