Screenshots of what you're doing.

Monad: Good screenshot. You have sth wrong with the texture above the doorway. I suggest using brushes only (patches are dificult to texture properly). With 4 or 5 brushes you can achieve very realistacly looking curves, it takes more time to model it but its worth doing.
Don't let players and yourself as a mapper get discracted by fully-detailed textures. Make sure you have finished geometry, then place detailed shaders only in places when you feel they need to be (not everywhere obviously). This screenshot look promising. Good luck!
