Thanks Creavion, I know that I should avoid cube rooms, but I was worried with the BSP Holes there, and a minimal BSP hole can lead a server to crash in a SLV server, for another hand, I was trying to do some cool archi affects and light effects in this map, like in first pic (the bridge) I was trying to do a good effect of heavy fog/smoke in the ground (not true fog, just a trick that come to my mind to do with sheets and it worked very well).
In the 2nd pic, it is a big hall to fly, but in this one I was trying to aplly good looking pillars on the sides, along with a bridge in the middle and something like, I don't know if you understand what I mean, a passage aligned perfectly with that wall texture (the end wall).
The 3rd and last pic (the flag bases), I don't like to much either, due to that same reason: to cubic. And I think that they are really ruin the entire map, but like I said, as it is for SLV, it's better leave it as it is.
Well, I am actually building this map in a attempt to apply some stuff that I learned in a lot of different tutorials (yeah Creavion, I already read that one, and even the Hourences one, they are both very good).
Next time I will try to build a MH map (non SLV of course) and apply everything possible that I learned and create my own style.
P.S.: Creavion, what do you mean with "trim lights"? I don't know the concept (maybe it was in one of those tutorials and I can't remember now, LOL)
but at all I dont know anything about mapping... 
Anyways, i've to say that the first two shots looks intresting, but i think 3th shot looks a bit to bright for me
It could be more interesting if you make it not so symmetrically.
