Lions Arch Texture modding

Trying to make LA look more snowy, main problem so far is that it doesn't render a large enough distance :(. What is possible is altering every little bit of land, however that'd take aeons, I'll see how far I'll get :D Note this is very much a starting point and I've never done this before so god knows when/if it's done.

(and yes, I'm aware I need a new computer)
