Ohh, this is much improved; I'm glad you listened to the advise gained from the first winter assault.
A few points though:
The map seems rather dark, almost pitch black in places, which looks strangle against a day time sky box. Are you mapping with r_gamma set to 1?
The layout, while greatly improved does suffer in a few ways, the ctf spawns and flags are both on top of each other and at the end of a dead end, a very long dead end in the red case. CTF spawns and flags should never be directly on top of each other, or in my opinion within line of sight of each other. The flags should be in an interesting area with a number of ways in and out.
Theres lots of falling snow, but not so much on the ground, ok theres a bit on the roofs and besides the paths but it just doesn't feel like enough considering the amount of snow fall.
The skeleton on a spike is missing its texture, yet the one in the well is textured.
The black bomb site in not visible and the red bomb site is only partially visible.
The light flares, while a neat touch, I find them a bit excessive, maybe darkening them would make them a little more subtle. Also the flare texture doesn't reach complete blackness at the edge so the flares actually appear square up close.
I'm looking forward to beta2
