Pros: It's a very interesting map, it's an overall good idea. The textures are balanced well, and It looks very nice along with brush structure.
Cons: However, there is very very few cover spots, it looks like it's just a straight away spawn-kill fest. If gameplay wasn't in the criteria, this would be a highscoring map.
Improvements: Add cover, add interesting objects and structure.
Aim_ag_texture_funpark is a really good idea for a map. It looks really good, but I would say, to make it look better is to add a 3D skybox, for that would just be pure hax. Also, I recommend adding some more crates scattered throughout the map because it doesn't seem to have any cover. The map seems to just end up in large shootouts from one side to another.
Definitely keep up the work. It's amazing.
