the 5 was a really good start, not too hucked or penciled. just try throwin in easy little grabs like a safety or critical or somethin, basically just try to touch any part of your skis in the air, you'll probably miss the grab but it will make your spins get a lot more styleish and controlled.
A good start, keep up the good work. Filming wise, use a tripod if you have one and play with some different angles. Skiing wise, keep practicing. As for the edge shot, rails can be hard on skis. File your edges down, get an older pair of twins for cheap if you don't want to use your good skis, and if your edge gets dinged, cut off what's sticking out and epoxy it yourself. Usually you'll get a couple years out of a pair without too much repair work.
