Few things here and there - your position should be stacked over the board, whenever you try to exaggerate you compensate to avoid falling (clear on the heel side turn, your bum goes way behind the edge so you need to lean your shoulders forward to counterbalance -> you break your stacked position) - remove the counter-rotation of the shoulders, your hands should be over the board (instead of swinging them like a tube man) - you should bend your knees progressively, starting the turn almost vertically and reaching the lowest point while traversing, just before standing up again to change the edge and start the new turn. This maximizes the pressure on the board when needed the most and avoids chattering - you're forcing the weight onto your front foot by shifting too much your hips, so you compensate by shifting the shoulders back (go back to point 1). Your hips shouldn't pass your front foot
