Overview would be good, then I would be more inclined to download it.
Anyway, the map is good for a first map, in that you actually thought about a (relatively) new idea (flag passing). Execution wasn't so good though, there is far to many stat guns, spawns and you didn't need to have so many routes, no-one would go down to the bottom, unless the flag was down there. Everyone would try to go through the top route, and it would be chaos.
I won't be redoing this map.
