Just a word of advice, competitive players generally don't like snow or night skyboxes in maps, and your map has both. Night skyboxes make it very hard to see rocket jumping soldiers or demomen, and seeing that that's a key part of competitive TF2 I'd predict you'll get requests from competitive players to change the skybox. Snow apparently can result in low fps (although I've never experienced it myself), and also makes it hard to distinguish between players for colorblind players.
That's just my two cents. Maybe you'll want to talk to Scorpio or someone else with a lot of competitive mapping experience under their belt.
This is true. I had this feedback for stark when I moved it to competitive testing. snow and dark -> major contrast issues.
