I usually find something good in any mapper's work, but you make it extremely hard. Well, finally looks like you are doing something your own?
Firstly go and play TW, I can hardly see that you know what's that gamemode from this design... This whole (stypid) gamemode's specialty is no jets and realistic mode, which leads to that you can have only one route and buildings on it, also you can't have sharp cliffs as players would do suicide when they drop down from top. Yes I totally agree with L[0ne]R, go and make dm instead.
