What makes a Skate video great?
First, you gotta be happy with what you've done, your work. That doesn't mean you don't have to overcome yourself every edit with new things, new techniques or just different results, because that may lead to a state of resignation and self conformity, which it aint good.
The way you use the spots, the way you film the tricks, the tricks themselves, why you did that trick instead of the other one. The soundtrack you pick, in the case you feature music in your video project.
But the most important thing, have fun.

Nah, the most important thing, you gotta be in a team heh.
