Style depends on what you're personally going for. The goonskate community seems to like fairly realistic videos - but it also seems to favor gimmicky skateboarding in a lot of cases, in my opinion.
Personally - the revert out of the 50-50 was a little sloppy to me because you turned while you were on the rail, which always looks strange to me.
Your camera work wasn't bad, per se- it did its job - but mastering the advanced freecam will open up a lot of possibilities for you. It's worth experimenting with.
All of that said....do what you want to do, and don't let the haters get you down. Trying not to "suck" for your own sake is one thing, but don't do it if you're just trying to impress the community, y'know? It is, after all, just a game.
