Hey guys,
I did that a while ago, and found interesting to share it:
thanks!
Holy smokes.
When it’s foggy you don’t exactly see big clouds infront of you; your vision is just limited by a cloud:
I guess this is OK for the dusty sort of fog in desert-like places, though (because that makes sense in those cases):
Still, this is pretty cool.
The smoke is just here create a creepy atmosphere 
But ye IO agree with you
