Awesome (but small) map! Gameflow is good, and theres enough space for dodging / moving.
However 2 things.
1. How bout making those jump pads a little more spectacular? e.g add a thin line of a lit up texture beneath it or something like it.
2. The "grassy" part outside that u can see when u jump at the windows is either textured in a weird way or not completely recalcd cuz I get like two shades of some weird green (maybe its also my machine...)
Other than that awesome! I love it that there's details even where the viewer doesnt pay so much attention to (eg the fan far up with the smoke particles, or the sewage system with the water tunnel ;) ) I love a mapper that pays attention to those details!!
4/5 from me for now, great job!
