It's actually rather hard to tell just how far forward you're leaning from that 45 degree view, because your side lean exaggerates what we see from that perspective. If you could get a direct side view at the line, that would be ideal. Until you can see yourself from that angle, I don't know if I'd try to change anything.
Most of the guys on tour lean quite a bit. "Nose behind the toes!" was always the mantra until the modern pros came along and changed everything. Take a look at Jason Couch, for example (Click here)
. Advance the video frame-by-frame using the arrow keys (I love Quicktime; I sure wish Strikepass used it). While he is an extreme example, is anyone willing to claim that he's losing leverage at the foul line? And he's not the only one. Most pros deliver the ball with their nose in line with, or past their sliding toe.
Ditto on the ball-dropping thing. Try more tape. If you were a squeezer, it's going to take more tape than you think (I used to be one as well). Add tape until the ball feels like it's hanging up a bit, then leave it there. Throw a few more, and just try to relax your thumb as much as possible. And don't just add tape in the front and back, either. Stick your thumb in the ball, and look down the hole for gaps, then fill them. Cut strips of tape into thinner pieces if you need to. The hole doesn't need to be especially tight if the gaps are filled properly. When I release, I feel a slight tug at the base of my thumb. Not so much as to throw off my swing, but enough to let me know that I have a good fit.
All in all, I thought your approach looked great; very smooth and effortless. The only thing that jumped out at me had already been mentioned; the push-away. Mo Pinel promotes what he calls a "sliding hinge" type of push-away that he describes in this article
. It helps you maintain balance and orientation. What I do is that I keep my balance arm hand on the ball until it begins to decend. That keeps me from pushing it out too far, and promotes the "half circle" motion that he talks about in the article.
