PinWheel Help

So, again, I’ve been starting 5A. And I need help with Pinwheel… Is it practice or is it just me?
When I do my pinwheel, yes, I’m afraid of hitting myself/things. But I don’t pinch.
And I try and not flinch away. But, every time I do it, it’s a short second when my string/yoyo/counterweight is in the air. And my string is always short, no bend like there is in the tutorial. Any suggestions/tips/pointers out?
