I would lower the anchor point. Personal preference but may make things easier. I think it sounds and looks ok. Lighten up a touch, not to much on the pressure.

I also believe if you made it this long on your stropping you are doing fine. Stropping is not the only reason new guys dull edges. The angles you took early on did not help the edge and your stropping kept that edge going for a good while.

Keep at it. You are doing fine. Stropping does become second nature and then one day it just does not go well. The next day you'll be fine again.
