I didn't decompile to check things out too much. But from looking at it, it looks like a lot of small brushes are used in places where they don't need to be. Little overlaps and things like that. Use a bit more carving when you can to keep the count down.
Aligning faces and textures, everyone messes this up An easy way to fix is by dragging the block around until the texture looks right, then lock it with alt+L and drag it back the place you want it.
Not sure if you used detail brushes or not, but make sure to use those on most things that aren't vis blockers or walls/floors/ceiling. Although it won't matter much in a smaller map like this.
The lights on the wall seem to glow a lot compared to the type of lighting the map has. If you are using sky lighting, you don't really need the lights to have such a high setting. Did you leave them at the default of 32000?
Flag isn't reachable for anyone that can't jump. Limits who will play it and enjoy it. But, it is fun to jump around on this one.
It's pretty good if this is your first attempt at bsp.
Ahh, cheers ace. (Long time no see.)
Yeah there are quite a few small brushes in places where it could've been avoided.
I did try to align the textures (Or most of em) must've missed some
Yup, i left the lights on the wall at default because i actually started out with pbsky3 (Night) and it looked awesome but, then i fixed some leaks and yeah. went too dark for some reason still trying to work out now
About the flag i suppose being a jumper i find that jump very easy (Kept overjumping tbh) but, yeah i need to remember not everone can jump.
And last but, not least. This is my first attempt at bsp

{EDIT}
Forgot to ask, what do you mean by "Detail Brushes"?
