Slow rotation

Hello,

 

When I'm doing most tucks I'm too slow in my rotation. My twists are quite fast (I do realise they're two different things, I'm just putting it out there) but when I'm doing anything else like a webster, side summy, etc.  my rotation is slow and I don't land the move.

 

What can I do to improve?

technique and power

Could be a number of things. We need to see a video to give you good advice.
