Future TP -
As noted before it is a little hard to analyze your swing with the camera angle - glare from the sun doesn't help either (even when blown up full screen, I struggled to see details). I think garybbq is right in that your grip appears to be on the stronger side. And as you noted the transition is a little quick.
Neither of these are really an "issue" is terms of your stock shot shape, you'll just have to be aware and learn to stay on top of your tempo depending on how stressful the situation. Everything else looks fine to my amateur eye (from what I can see) - setup, posture, angles, swing plane.
I am curious though - how comfortable are you with hitting fades, both low & high with your swing? Given where you want to go, you definitely want to have these in your arsenal.
