Holy shit there’s a period key for a reason.
Also this map looks REALLY blocky and the texturing is horrendous. When you make your walls make them realistic - look around your house and estimate wall sizes from there. Walls are not usually 5-feet thick, and ceilings aren’t .05mm thick either. Additionally, buildings usually have floors, not grass, and rooms are generally built out of the same wall material, or at least painted the same color. The textures do not line up with the ground, and sometimes tile oddly (Specifically the brick one that has a bottom to it that is repeated as it goes up the wall). Align your textures with the floor and think to yourself when selecting textures “Will this work if it has to repeat itself?”
What I think you need is just a bit of practice, and to really polish a map and get it to look good before you release it. If you’re looking for mapping help, the half-wit tutorials can really help you out and teach you some of the more complicated bits of mapping. http://www.halfwit-2.com/?page=tutorials
