It's cool to have a little map to train your clan on and such, but I don't know that you really want to release it publicly.
Since you've posted it, though, I'll give some feedback:
- Linux is case sensitive, so you should keep your filename lowercase.
- Making text out of brushes usually looks bad. If you really feel the need to do it, spend some time and make the letters properly proportioned and whatnot.
- Wood grain should almost always be aligned along the length of boards.
- The lighting indoors is super bright and completely washed out. Try using multiple, well-placed, darker lights instead. The lighting in general needs a lot of work. Lighting can really make or break a map's visuals.
- The transparent yellow boxes don't work very well to jump on - they're visually difficult to determine when to jump in your peripheral vision.
- Needs better texture selection rather than solid/riveted metal everywhere.
