Okay so this isn't really something that I made myself. The actual snow simulation was created by Disney for the movie Frozen. What I did was try to find a way to take a shot from the tech video and composite it into something else. Here's the original youtube video that I was able to get the asset from.

That's all really. Was just inspired to try and see if it was possible.
