It’s not that clean, smooth that stuff out!
And you might want to wear a dark shirt and use light colored string next time.
mista8eight8 has a point: it is very hard to see your tricks. Why watch a video when you can’t see anything? Use a dark shirt, like black, dark brown, or navy blue next time and a white string to show some really good contrast, that way we can see the tricks better.
Also, edit out your mistakes! While you shouldn’t be reliant on the “Cut” button, feel free to use it, so that you can show us what the trick should really look like, regardless of a mistake. Feel free to do tricks more than once. We’ll never know!
Errr, nice song
Also shorten that string. The you can be faster. It was also to dark. I feel bad because we’re all trolling on you but…
“do not tell a man what he does right, but rather, what he does wrong”
then I would have no friends. 
I don’t consider this trolling more of helpful suggestions. But that’s just my opinion
