Love this map, and I love the theme. I know I've said these things a few times already during tests but I might as well repeat myself. Sorry for the lack of screenshots, but I've got a splitting headache and I don't feel like loading up TF2 once again tonite.
There's a sightline from the bridge on the left side (facing cap 2) where BLU snipers can easily spawn camp Red with a sniper.
Caps 1, 2 , 3, and 4 can be too easily taken by BLU team because of the amount of pathways they can access to it. Red team has a hard time defending without the use of a turtle. The worst of them though is cap 3 and 4. I'd suggest in the case of 4 removing the high ground passageways that BLU team can take or making them easily accessible by RED team.
Finally, the red glow on the last point. Makes it difficult to see what's what.
