What do you think needs improvement?
I think it looks pretty good. Few things I noticed, in no particular order.
1. Hunched over and static upper body. Makes it hard to really get into those toe side edges especially. On toe side drive the hips.
2. You are unweighting by standing up/cross over turns. Try unweighting by dropping the knees/crossing under.
3. Heel side on steeper terrain in video 1 -- you are opening up and looking down the fall line instead of looking across and keep your body in line with board. You wash out a few times doing this.
4. Doesn't seem like you are getting the board on edge and carving. Get lower on heel side, and drive the hips on toe side. Let the sidecut turn for you. You'll feel the difference in board feedback almost immediately on a well weighted carve -- it's like the board just wants to shoot in an arc.
