That's really nice to see beginners in mapping making their first map with pretty decent graphics thanks to that automapper, we used to see lot of ugly ones.
Firedead: there's obviously lot of points to improve your map, even if this isn't bad for a beginning. There's only one point I want to mention about mapping: you're obviously mapping directly with the editor. To map is not to fill a quad. You need to think to a first prototype of your map on a sheet of paper, and then to reproduce it in the editor, and improve later on.
Not Luck, Just Magic.
