Looking good, David.
One thing that helped me get my head down was thinking about pointing my chest at the centerline of the bike, rather than the ground. I realized while watching motogp one day that this is what the aliens are doing... it's like they're hugging the bike.
I tried it on my next track day and it was a huge difference. Trying to move laterally without also dropping that inside shoulder was much more awkward.
See how the sternum is pointed at the long axis of the bike? This is really consistent when you watch with that in mind.
