Aim_ag_texture cams is quite an interesting map.
Instead of following the default pillars of regular maps similar to this, it implemented a camera.
Nonetheless, I'm sure we can all say that the creation of the map didn't take that long, but the idea is solid.
To improve this map I recommend adding lighting (definitely), putting in a 3DSkybox, and moving the pillars in a oblique fashion. I also recommend changing some of the textures because they can get quite... well, annoying.
However, I have to say it's quite a good idea, and definitely good for things like GunGame and Deathmatch.
