The geometry looks good from here.

I thought your back foot looked a tad too relaxed towards, but it is difficult to see in the video how hard your feet are working. Ideally it should work pretty hard until the hands are past the right hip. If you feel that you have more distance in you, maybe you should practice swinging (or is it hitting?) from the feet.

7-17: Halting the Backstroke motion with the Feet and letting this same tension pull the Downstroke through Impact is "swinging from the Feet" and gives the Stroke maximum Swing Radius.

In my personal opinion this is also a requirement for obtaining maximum thrust. It's the ground force that everyone is talking about these days. If you're not doing this already there's at least a club length in engaging the feet properly.
