Enough of this monkey business!
I actually learnt The Chinese Bit as a teenager (yes, around 30 years ago, the effect really has been around THAT long!) but I never performed it much. It didn't seem to matter how slowly I did it, some specs just couldn't remember which coin was supposed to be where!
If you want a bit of constructive criticism...
I think you seem to fiddle about a bit too much in your closed fist, you need to slick that up a bit so your fist appears more natural and it doesn't look like you're doing 'something' to the coins, especially when you're taking coins out of the fist.
Also, I personally prefer the coin to be tossed off the back of the fist (as originally routined) rather than taken with the fingers, I just feel that taking the coin looks like a cover for a 'move'. Personal preference here though.
Finally, maybe trousers with bigger pockets would be an idea!
Nicely done though, I'm just nit-picking.
Cheers.
