Quake mapper, new to UT99 here \o/
What goes attached here is the blockout of my first UT99 CTF level, without any art or even proper lighting, but fully functional as far as I could test.
I most likely made mistakes and/or things could be done better. So I came for advice from UT99 veteran mappers

So, what is right and wrong about my level, items, navigation points, paths... ? Any feedback would be much appreciated.
EDIT: This is just a blockout (or "greybox"), the level won't look bland, untextured and unlit like this.
EDIT: I updated the level in 09/2 correcting problems commented here and improving the level itself. Red base site was poor and funneling bots in a narrow passage, surprisingly making it harder for the red team to defend their base. The space is now expanded and more interesting.
Thanks!
