Played it on gameday and it was fun, but you still have some work to do.
Here are a few things I thought while playing this map:
1st -
Sightlines.
It´s a good thing to have a few good areas here and there for Sniper to get good headshots but, these were unfair in my opinion.
2nd -
A lot of the time I never even wanted to put my foot in this path. It is very small and it just tells me death.
Almost everytime I did go in it I was either very lucky to survive or killed by Soldiers and Demomen easily.
Now I´m not sure if you want to keep them and try to fix them but, I´d suggest maybe trying to just cut them out.
3rd -
The brick texture on the bridge.
I´m probably not the only one that said it already, they just don´t give the tf2 feel where it stands.
