Surprisingly before I played this map, I was playing on Windfall and Intermodal, both 5cp maps so I didn't expect this map to be 5cp too.
I have two things to complain about:
Add some lighting in that hole. It's kinda hard to see where you're going unless you turn around.
And then finally, this map is really... really big or maybe overscaled. Don't know if intentional or not but I think it needs to be scaled down a bit.
Unfortunately I don't have much to say as I'm not an experienced mapper.
