The opener had a lot of speed, but:
It looked too stiff and cluttered.
You switched your movement around for that grab.

You lost a lot of speed after the grab, thats what grabs do. The kick itself was ok, altough I would nitpick at how it basically dragged along the whole arm before dming the arm. You have a nice transition to the second kick. The second kick itself was done by the shin, which is not preferable. Last kick was ok.

You definitely have potential.
