3rd person WIP

I have recently been working on a 3rd person shooter/runner. This is a new project so I do not have much done yet. I am trying to make it look like an alien ice world with things that look like temple ruins. Any feedback is appreciated. And if anyone can tell me how to change the sky color/appearance and how to make blizzard fog, that would be very helpful. I will post updates and changes since this is in early development!
