It wouldn't be too bad, but I could see people camping the stairs a lot. You should add an entrance in through a balcony of some sort or add a hole in the roof/wall. Along with some boxes to act like stairs or something.
Add some colliders in the form of boxes, and upturned couch, a bench just something to break up the corridors even if it's only a little bit. other than a few things it looks pretty clean... A bit generic.
Pretty it up a bit, add some alternate paths to the flag, and give bravo some type of advantage by giving them some cover, perhaps in the shape of a single story house/hut?
But I think it's pretty good.
Also, it looks a bit small from the screenies...
Edit: When I said add some balconies, I meant on the side for bravo to access.
I like it though, It needs a few "Things" but I like it's potential. (And It looks really clean and crisp)
Edit #2:
Can I suggest maybe adding a tunnel under that leads into/near the cellar to give bravo a chance to flank the reds, or to escape being crushed by spray?
