Seems like my previous post here was totally offtopic and not after thinking and not intelligent, too. OK - I'll try to correct it.
Maybe You could add at the end of this map presentation (portfolio) something like "overview" - like this type of view when You are as a spectator (You know - this bmp overview) . But at this overview should be shown some important points - CT and T spawn points, Hostages points and Hostage Rescue points. Maybe even some 3D overview (like rentgen-radiograph of all at this map) with all map at one screen. This map is really big, so maybe this could be helpful for players starting the game first time at this map. Me probably - I'll be losed in that labirynt after 5 minut playing without any idea where I have to go. But it's maybe because I have some problems with my space orientation.
