The camera is at the wrong angle this effect is best performed straight on.
The first coin was good. Maybe could have been better if it was shot straight on and not to the side.
With the second coin your right hand needs to stay over the bottom left coin not move over to the bottom right.
Third coin would have been perfect if you had performed it a little quicker.
Maybe I'm being picky. I never really perform this effect so feel free to tell me to shut up
Apart from that it was very smooth and one of the better performances I've seen.
