I would work on updating this map more. Your first release is missing textures in the map that weren't packed in. Honestly, its an alpha release though, so worry less about custom content unless its vital to game play.
First point is rather flat. You should add some height variations rather than leave it broad and open
Its not very obvious to me that you could also get on the red building in the far back of the first picture i posted.
The area after the two ramps, which I can't tell whats going on is going to be tough to game play. The trail sputters out for a distance similar to Snowycoast, but there's no cover at all. Its kind of out there, but you don't want to have blu have the advantage with spawn camping to push forward. I would at least add a ramp or something. Experiment with heights add a building in at least to change the layout because there's nothing interesting in terms of game play for it.
I honestly couldn't after the first point where the other ones were until the final.
The final is going to need a lot of work. Blu can attack and hold off the defenders pretty well from the top of their spawn. There's also a lot of open area, and no cover at all.
Need to repack some stuff here. To check if things are packed type sv_pure 2
You sure you playtested for bugs this? It looks like the cart will get stuck on this spot. (also long sniper line from here to blu 1st spawn)
There barrels, are we allowed to play up here?
Disable shadows on the tracks.
These two paths are awfully close to each other.
These two props intersect each other and look awkward. Also, use the wooden latter. This latter is more of a decoration that clings to the wall.
This spot here can cover all three doors at once.
