Congrats on getting 'em back. Mental blocks really suck, almost worse than injuries.
Looks like you're getting pretty good rotation. But I think the main problem with technique is head-chucking. Basically you're throwing your head back before you even leave the ground, then as a result you only get a partial tuck.
Try focusing your eyes on a spot on the wall in front of you, then keep looking at it and you jump straight up, swinging your arms, then when you feel you're almost at the apex of your jump, pull your legs up to your chest into a tight tuck. When you see the ground, start to open the tuck and you you rotate around, look for that original spot on the wall again.
Hope that helps!
