im new to map making too, but one thing that i noticed right off the bat was that you can see the trigger tool that is in the box enclosed in the glass, and that it extends well beyond the walls to the map. Textures need work, even im not great at that yet. Other than that i cant say anything else since its a small map, and i dont know what you are trying to do game play wise. Keep on working on mapping I know i will!
