The left leg is worst of both worlds in the drives. Not the Feldy type of kick to the right counteracting the force of the elbow chop and wrist snap or staying on the ground pushing forward adding power until the rip at the very least. Now the leg acts like an anchor slowing your rotation and not adding to the weight shift.
You putt too well already

But your stance doesn't seem to be the most stable. I would test a little more separation between the legs sideways and adjusting the torso accordingly so that the chest is square to the target. The mellow arm motion conserves the arm muscles but eventually if you tire out or just miss out in power generation the slow pace of the arm may go even slower and lead to the elbow straightening before the release. Then the momentum goes the way of the least resistance which is flapping the wrist to the right.
I wonder why you posted the putting parts, because you are a good putter as it is. Many would say a great putter at least on a good day. Is there something specific you want to improve on? I'm thinking why change something that isn't broken in the middle of the season or at all? Sure there's always room for improvement and experimentation but please do also consider that are you able to revert to your current form without damage to your form and confidence if you try out new ways? At least if you give a lot of practice to a different form. Everyone can benefit now and then from excelling in both straddle and stagger stances. A straddle stance is superior in uphill and wet weather putts. There is a lesser chance of the legs slipping and changing the throw.
For added distance you could straighten the hips faster and start the arm putt lower and raising the arm higher with added arm raising speed. And a faster elbow straightening like a punch and quicker finger spring would also add accuracy and repeatability as long as the added effort won't tire you out prematurely in a tourny.
Flat shots need running on the center line of the tee and planting each step on the center line. Anhyzer needs running from rear right to front left with the plant step hitting the ground to the left of the line you're running on. Hyzer is the mirror of that.
