nice first map posted on quadro (even im sure this isnt ur really "first" map ever made, what would be even better ;P)!
the geometry is pretty good, u know pretty good how 2 trim edges.
the clipping/noclipping can be done better (like some trimmed edges r noclipped, and some arent) but i dont mind keeping the sidewalls of the map unclipped (makes it pretty nice 4 trickjumping 2 :D).
the detailing isnt very well, u could add particles to some tubes (maybe even mapmodel 158 and/or 159), but a ventilationshaft would be nice 2.
the gameplay can still be confusing, because some tubes there r teleports and teledest close 2 it, but some arent (maybe u could try to add a different texture or different shape to the teleport/teledest tubes, or to the no-teleport/teledest tubes, so the gameplay gets easier, and increases because u have 2 think less where u gotta move).
i think it would be more realistic to if u make that the tubes arent "pasted" with some kinda glue to the building, but r really comin out of the building.
further, i think this is more some kinda industrial theme, with a mario-touched gameplay (because of the tubes of course :P).
anyways, nice map! keep going like this!
ill give 60points 4 it.
