Here is an example.

this really doesnt look good does it? Where is the light coming from?

What you can do is, you can add trims around the walls, split the wall up and add multiple textures instead of the same one tiling over and over again. Add some lights so it makes sence that theres light there.
Heres what i did with it.

(look at the bottom floor wall, mid wall, and the ceiling. Its not all the same texture).


That is a lamp or spotlight. Not the sun. (I get that shine effect from using corona settings on lights, might post a tut for it later).

Some light trims.
If you dont like what i did, think its too bright w/e, go play on screenshot 1.
Anyways, i hope to see much more detailed and more time spent on maps in the future
