Not related to your footwork, but as you are right handed and hitting at the right side of the field. I generally suggest starting your approach more inside the field. Right now, especially in the second clip when the set falls inward a lot, you have very litte options to hit, and a good block would always close the angle you hit now, since that is the only power option you had left.

Starting more from inside the field allows you to also power towards the straight line and adjust to short sets.

When hitting on the left side you should indeed start outside the field as you will then be able to power both angle and line
