wtf?
if the problem comes from the multiple pop-up windows, its from the host, aint my fault…
One assumes you chose the host though?
Anyway comments on the actual pictures now 
General:
- Damage to the buildings is a bit too blocky. You aren’t the first to fall foul of this, but it’s very commonness kinda annoys me.
Buildings don’t just have huge blocks taken out of them, nor do they generally end up balancing in improbable structures
- I like the scale. Nice and high surroundings, and it’s not fogged to hell and back either. The snow fits in with the map, unlike a few snow maps I’ve seen in the past
- Some very nice custom textures - always a good sign
- Something I don’t like generally in snow maps is the ‘purity’ of the snow covering. Where’s the footprints, the slush, the bits missed? Same for winddrifts - pick a rough direction for the wind to travel in, and bank up snow in that direction, and remove some of it in the opposite.
Image specific:
2nd pic - Looks like the left side of the main building you’ve repeated the texture too much horizontally making it look thin and disproportionate. Not 100% on this, you may have a FOV I’m not used to looking at though. That chunk out of the corner is particularly ‘neat’ 
4th pic - Unlikely looking bit of damage. I do like the spikes on top of the wall though - definately makes a change from the usual flat alpha-ed version most people tend to do.
5th pic - looks like the windows go into the concrete supports. Just shift the window textures down until they are more central on the levels.
6th pic - neato damage again (won’t mention it any more I promise!)
7th pic - building on the left looks great with the new textures
11th pic - would definately put snow drifts over the plane - looks like it’s been gently laid on top of the snow
12th pic - select the faces with the light, bring up the texture editor (‘s’) and hit ‘fit’
14th pic - empty-itis
15th pic - like the stairs - stuff like this makes for great non-horizontal firefights 
Good to see the railgun getting a home at last 
Just a word of caution:
it will be tested on some local servers to check if everything is ok, and then i will release the final;
I hope I misunderstand and you mean you’ll be testing it with lots of friends on a LAN, otherwise there’s no way a map is ready for final with that little testing. Releasing a map as final without properly testing is a good way to earn a bad reputation, so if you can avoid it, you should.
Looking forward to playing it though - seems nice and large and I like large maps these days
