My input is learn "air awareness" what I mean by this. My 1st time I'm looking at the transition of the ramp next thing I know I'm riding down the hill. I completely blocked out anything happening. As I went a few more times I was able to see what was happening and spotting my landing.
This was key to me as I started to get better and see what was happening on each jump
Good luck start small and build up.
