First off, I would like to say this is an awesome map.

My first thoughts were "beautiful!", then "how does it play?" then "hmm may be a little too CT sided"
The thing with this map is, it has a perfect mid, it's so great, many spots to smoke off on and the possibilities are endless with what you can do.
as for map balance, it does seem a little CT sided at first, it's VERY hard taking A site, as for B site, easier... but I'll talk more about that later.
as I played more of it I decided that to play as a T, you always need the mid control, without mid control, you can say goodbye to an A take, I like the fact that the T's have the height on their side looking down mid.
as I played this map more and more I wanted to find bugs and boost spots and even try out a few smokes.

This is what I came up with.
B is an easier site to take but you cannot smoke it off without actually being there
A is very hard to take however it is easy to smoke off all the CT vantage points without actually entering the site.
This kind of makes each site evenly layed out, as CT it is similar difficulty taking back both sites, this overall makes the map quite even in theory so I'm hopeful it will do.

it is a very beautiful map, tons of clever boost spots, lots of potential for smokes and very professionally made, the backdrop is stunning.

While I was playing I noticed a lot of smokes to A site bounced off invisible walls and it was quite annoying seeing as it's such great site to smoke off.
I suggest you open up the skybox a lot more for A site and make more open, this would add to the gameplay extremely and improve things greatly. (i hope this is possible)

I've had quite a bit of fun playing this and I hope it'll be included in an valve operation, I did think of this while playing and decided to find bugs/glitches and things that should be changed/fixed.

Here are some pictures.
(you can see the location on the map to fix these issues)

2 man boost spot to lower window reveals this texture missing, could be used as an exploit to see rotating/pushing enemies.

you can throw the bomb up on top of that plank, griefer central.

There are quite a few of these dotted around the map, makes you feel like you should be able to jump into them, not so. maybe fill them, or allow the player to get inside?

This is the biggest bug I found on B site, jump crouch through that window and you fall into a small room and can protect the whole site whilst being invisible.

These metal sheets have no collision, making it easy for someone to completely hide in them.

I feel I should be able to jump ontop of these, I can't. invisible wall.

here aswell, I can't get up there. perhaps fill it to avoid confusion?

not really needed as a fix but if you jump at the wall in terrorist spawn, really weird place as you can see, perhaps needs patching up a little.

another invisible wall :S too bad I can't get on the bath.

no collision.

I jump on... these tools get in my way... not smooth... RIP me.... (tools have collision, please fix)

two man boost on to a small ledge, can then jump and glitch around the corner and get into some game breaking spots. (i suggest removing the collision on the ledge)

as you can see here, the positioning from that simple boost as listed before, can put me into this spot.

these air fans all have no collision, in some places they can be used to hide part of player's bodies, also quite annoying if one wants to bounce a grenade off one (doesn't work)

clever boost spot at back of B site reveals missing texture ontop of the arch.

and lastly, probably not worth fixing, but I noticed these boxes where placed slightly above the ground, hovering slightly in the air.
quite noticable when coming from below the steps.

And that is it, I hope these pictures where helpful in perfecting this awesome map.
Thanks for reading!
