Here's my feedback:
-The map needs more height variation. There's only one way for non-jumping classes to have height advantage and that's only really useful to snipers. Consider raising the point and maybe the spawn buildings.
-I really like these health shacks.
-Some of the pipes in mid have broken textures. Make sure you've packed your map correctly.
-There's a sightline through the health shacks.
-I feel like there's too much direct access to both team's spawns from mid. Spawn camping could be really easy on this map.
-I like the aesthetic so far.
