Just played this on the EU game day, while it looks absolutely amazing, I still feel that there are a few visual and gameplay improvements to be made.
CP1: On our first round on this map, the enemy team captured the first point, and they were stuck there for a while trying to take out the sentries and other obstacles, this narrow passage where the cart was appeared to be the only obvious way to go, besides a pathway blocked off by a gate, which if I recall doesn't open until CP2 is captured.
I also noticed several displacements had gaps showing the skybox (very thin-lined gaps but gaps nonetheless).
Other than that, a visually amazing start to the map.

As I progressed I soon came to the most evil staircase I've ever encountered in TF2 so far: there's a large clip in the middle of the staircase, unjumpable, you have to crouch to the very edge of the staircase and slowly walk up and around the box, standing over this part will show you just how bad it is, I believe I have a screenshot of it:

Somewhere between CP2 and CP3, someone was able to hold us off on their own by using their original spawn, the fact that they were able to use their old spawn put them at a huge advantage as the pyro was able to continue restocking and regenerating their health, making themselves seemingly invincible. If this spawn was disabled for red team when they move back to their other spawn in the final point, this capture area would be alot more fun.
Finally, there were general clipping issues with objects and such later in the map, mostly water that players were able to walk on.
But overall, this map looks stunning, and whilst there are a couple of major gameplay issues, they shouldn't be too difficult to resolve, hope to see this finished soon!
