My favorite part is the intro "Old Creepy Guy Butters" by your camera man.
It was a bit hard to see, but I think if you took a similar video on some more challenging terrain, just a bit steeper, your faults would become more apparent.
I had trouble seeing if you were carving or skidding. It looked like you were carving while going across the hill, but skidding in the actual turn. It could be due to the slope of the hill and lack of speed, but ideally, for a full carved turn, you would be traversing the hill going to the right on your toes, and switch to your heels while the board is still pointing right. Then you ride that heel edge all the way around, 180 degrees, until you are pointing to the left side of the hill. The sooner you get on that edge that will take you around in the turn, the easier it is to plant the edge and actually carve all the way around the turn, vs. locking in the carve after the board is already pointing down the hill.
