Posted by SyncronyzeAnd with 40% less ramp bugs than pancake :D
The geometry is really excellent here, and it's got pretty nice eyecandy. I think a little more "soft" textures (with less defined tilesm like the concrete) and maybe a bit more splashes of colour would help it a lot. I think pancake had a nicer theme, but this map definitely has better geometry. Overall, it's a good map visually but I personally liked pancake better in the visuals.
This map suffers from some sight reading issues where it's not immediately clear where to go, or what even you're supposed to do. For example, http://i.imgur.com/gtOPmUj.jpg at first glance, I found it hard to see what I'm doing here. There was a lot of turns where they were pretty blind. Overall makes it harder to learn.
I think it's an improvement from your last map. Keep it up.
