The lighting is very generic (explore other colors), and the walls have weird shadows on the edges especially near corners (third picture). Try disabling “CastShadow” on these parts and see what happens.
As for the build itself, the floor could use more detail rather than one flat piece. Adding windows would help too.
The map could use some textures on the wall and more realistic lighting. I’d add physical light fixtures so the player can actually see where the light comes from.

As well as the tip on the window, I’m planning on adding more clothing on that wall, however, the rest of the “house” has windows and a semi build garden that I’m currently using for my rendered models.
The purple lights are still bothering me. Change the white neon light color to purple or change the purple to white. Also make sure to enable future lighting if you’d like to.
The brick texture is also a too big. It is possible to have bricks like that, but I personally have never seen them used in that size.
