Yea man great job.

From b1 its been a little sniper friedly and its just cause if a sniper runs round he can get people coming ou of spawn, somthing just to delay him enough so it isn't too easy would be great, particuarry shooting them off the pipe.

Pros: The map looks great, that's for sure. You did a nice job of texturing and lighting.
Cons: There is no balance in this map. The only classes that really work well are Scouts, Pyros, and Snipers. It's frustratingly huge and needs more going on. Right now it's just a massive arena pit with a central tower.
Improvements: Flatten it out more, TF2 doesn't work well with vertical game play. Create alternate routes around the map, instead of a big ring around the circumference and a pit leading to the tower. The logs are a nice addition, but ultimately they are death traps. It would be more exciting if you forced teams to clash, right now it's just too open for any kind of an epic battle.
Notes: I wish people would stop rating this map based on visuals. I don't hate this map, I like it actually. I just think it needs a lot of balance work. Your detail is great, but game play lacks. When people rate it a near 10, it's not going to change a whole lot.

Pros: The map looks great. You've done an excellent job in texturing and such.
Cons: Those logs or whatever they are going to the point are too easy to fall off of. Arena already lacks health and this just adds to decreased health.
Improvements: Make the walkways wider and harder to fall off of. I think it's a huge deterent for players because the map layout makes you want to head to the middle point, yet it's somewhat difficult to get to as it's so high and all the pathways there are narrow. I think I'd even consider lowering the watchtower a notch or two.
Notes: I added the map to the rotation on my server. Since players get to vote for the next map, I've noticed that yours isn't getting chosen anymore. I'm wondering if it has something to do with some changes that need to be made. Let me know when you update and I'll be happy to check it out again.

Pros: Awesome on every level. Is one of those maps that might get included in a future TF2 update.
Cons: The spawn area gates look off.
Improvements: Try using the yellow gate model instead of a brushed gate. Is more TF2ey.
