My input / suggestions:
Cool KB pub map. lots of fun and very esthetically done.
I would choose playerclip from the tools textures and start going through the map...stairs..the RPG thingie (you can get in there and then you're stuck
), niches in the wall...everywhere. make it smoother for players is always a good thing.
I disagreed with some of the texture scales you used, felt some were to big (like that arches on the upper walls was way too big) but all and all it's cool and the map looks consistent.
The top of the spiral towers have misfit brushwork...showing gaps between the brushes, etc. i'd sort that.
FPS is super throughout the map and that's also good thing.
Keep up the good work. this is very nice job.
