Wintergate

I'm not sure what this zone is for https://i.imgur.com/w9VLPhI.png - If its meant for air, there's quite a bit of space around it to avoid the spot.
This map is really, really solid, but I'm not sure if there's enough of the map feature to show it in a unique way. Maybe adding one towards the side like this would be enough? https://i.imgur.com/bz0CTHO.jpg But if the goal is just to have the center path be InhibZoned, then this was executed very we ll.
The snow texture on the lowest level seems a little repetitive, you have a few unused textures you could replace to add a more simple texture ontop of it.
