Let's not obsess quite so much about pure mechanics.
Try to fall towards the target, not out to your left, and you'll gain another 10% more ball speed, plus you'll end up in better court position. Toss more right.
You jump fine, you swing fine, but at your height, maybe the idea of a perfect form serve like the pros is not needed.
The angle doesn't show how far you are leaning at your contact point...which is not so important, unless you really need to get to another level...higher.
