Hey Deh0lise,
I took some time to play 30 rounds on your map with expert bots - both CT and T. I'm a big fan of the art, texturing and the backdrop, very well done! The theme is nice too, feels cold, abandoned, remote. The shadow casting is pretty too 
I really like the layout - the up and down verticality is very well executed We don't see this enough in CS maps. The design is quick to learn, which is great. It seems like it would be a really fun map to play with the right number of people.
I do have some feedback, which hopefully is constructive for you. I guess I should mention that I've been playing CS since the first day it came out in 1999 - I've competed in leagues and tournaments and it's my all time favourite game . I've been designing a CS:GO map of my own for the past while - I always learn so much from other people playing my map - it's hard to see difficult areas for people when you know the map like the back of your hand 
Anyways, my thoughts - again just my opinion from my short time playing the map with bots. I have the utmost respect for your work and dedication and only intend this feedback in a constructive manner 
- I think A is pretty solid and has a fantastic unique feel to it. The design feels slim and natural, there's a good number of CT spots but also a balance of T pick spots. The open design of the site makes flashbangs and smoke grenade gameplay more interesting.
- There's definitely still some dark areas around the map - I know most people just drop their gamma to 1.6 anyways, but 2.2 (default) gives a better representation of how it should look. The dark spots that really matter the most IMO are the ones near the choke points, especially the train tunnels @ B could be brightened up as it can be hard to see CTs and gives them a bit of an advantage, when really the Terrorists should have the advantage for successfully taking the bombsite. (I guess Train's site A is a good example of this)
- I feel like some areas, especially around B could be tightened up. The site is a nice design, but um, I guess around the left/mid (from CT perspective) choke point and the upper walkway area for CTs feel a little large - and the actual width of the site overall feels like it could be slimmed down. I was playing with bots, so it's difficult to judge, but it felt like Terrorists maybe had too many places to look coming into the site (from both the direct path and mid access point).
- Mid is great, I love how CTs can hold and spot for Terrorists to cross. The cross to another path into B is fantastic, the idea that I gathered is that it allows Terrorists to apply more pressure onto B and give them an upper hand. I mean, correct if I'm wrong. I do however, have to say that I feel there was an issue with this execution on this. Mainly because this vantage point for CTs:[Blocked Image: http://i.imgur.com/lB3B5Kd.jpg]
I guess my thoughts on this gameplay area is that the angle is really awkward for Terrorists to cover while pushing into B. Assuming that they've engaged CTs in mid, and crossed to this area successfully, it feels like they should have a little bit of a break from combat - a chance to reload and collect themselves. Also for successfully crossing middle, Terrorists should be rewarded, and this area actually kind of puts them at a disadvantage. I feel like CTs should be fearful that Terrorists were able to cross mid, which should cause a rotate of CTs from A to back up B?
With that being said, I do see why this is here however, as it's off the main branch from CT spawn, and removing this would make that path only have 1 exit - however, I was looking at the design and thought perhaps a staircase placed here could replace this (please excuse my quick and horrible MS paint skillz

This is just a quick suggestion: I hope this makes sense and I hope you don't mind me giving feedback on this. Again, this is from playing with Bots so it's hard to determine how this area feels - but this feedback comes from an assumption I've made on this area and it's intended design which I realize I may have the complete wrong perspective on the design intentions. I absolutely mean no creative offense/disrespect, and would love to hear your thoughts!
-----
I think that's about it for the stuff I noticed - the map is very nicely polished and looks fantastic. The uniqueness of the design is great. I would love to play some time on it with real people or even test 5v5 - please let me know if you're organizing anything.
Keep up the great work!
