Paintball Omega

I'm making a paintball game where you choose what types of game you want to play (e.g. king of the hill, capture the flag, cops and robbers etc).
I'm trying to make it as real as possible.
There is a salesman in the conference room, you can buy soda, snacks, armor, and weapon upgrades from him.
You play all of the different types of paintball games eventually. After you finish one round you're brought back to the conference room and you vote again on which type of game you want to play.

I also made the camera view in third person, and you use your arrow keys to move.
The terrain isn't my best because I don't think a paintball course needs to be very heavy with terrain.
Opinions and suggestions are appreciated!

Screenshot descriptions (all paintball courses aren't shown, there are more):
1: That is the team arena, basicly it's just whichever team gets the most kills in the amount of time provided

2: That is the cops and robbers course. It's much like sheep tag, if the robbers are handcuffed then they go to prison, but fellow robbers can release them from jail by touching them.

3: That is the capture the flag course. I think everyone knows how capture the flag is played.

4: That's the free-for-all course. It's everyman for himself in this open course, and you score points seperatly which is different from the other courses in which you are always on a team.

Sounds good, but in the second screenie you should make thos buildings stand on dirt/grass, cuz they don't look so good...
