It's my school... The Casquilhos High School... It is almost done... I encrypted it because it was being played in a public LAN without my permission, so I encrypted it... You wanna play? PM me... I'll tell you the password... I'm sorry, but I was forced to do this... Sorry rowleybob...
Many of the textures look nice, but some are way to flat, too basic--like the window panes are pure black, and the desktops are a base color too. It all fits your theme, but it would better with some more textured textures in there!
If you plan on making this a playable hostage-rescue map, it would would probably be necessary to make the outside inaccessible--with your current level of detail in those windows, the wpolys outside are sub-4000! Or, you could simplify the detail of some things to make it more feasible to "use" the outside.
Lookin' good so far, keep it up! (If you PM me when you update the map, I'll add more comments if you want.)
Forgot to mention the scale in general is tad big, but not a gigantic deal.
