Now for the review. It shows that you're not an experienced map maker, so here are some basic tips:
Lay more polygons, so the map looks smoother and is easier to shade. Recommended tool:
Polyworks.
Shade the polygons with polyworks, so the map is pleasant to look upon, and also place sceneries. I recommend the
SML tutorials if you want to learn map making techniques.
Also, when making ctf, try to make similiar layouts to the default maps: have solid routes and well distinguishable bases.
Note: No negative criticism. Be as helpfull as possible, or don't post, at all.
