Too flat and inside on takeaway.
I'm not an instructor but here is a snap during your backswing vs a PGA player.
Hack2489, thanks. Good stuff. I have been getting lessons. He never even noticed. Maybe need a new coach...
Your swing reminds me a lot about my swing in the first half of my adventurous golf career. (I'm no pro, just a weekend warrior). I would start the downswing with a lunge of the shoulders. That's a tough habit to break. But, if I can do it so can you. Overall, FWIW, your swing looks pretty good. Others noted the flat takaway. That's not too hard to fix.
