Not bad animation
While the looks of everything and the wind sounds weren't great, the animated person does. But even as a trailer, it was pretty short, too. Plus, I can't think of a way this kind of thing can become parts of a movie. But then again you're probably thinking differently compared to what I'm thinking. Will there eventually be bloopers in the movie? Other than having the poor guy's parachute rope snap off in mid freefall? Because those would look great along with the actual movie. Well, I'll just have to wait and see what you can do then.
