To be quite honest I thought that was quite bad. First off, that's not a cardini change. Second, the camera was at the worst possible angle and you could see everything. Third, the way you were executing the change was just bad.
The angle was really bad, you were fumbling a lot with the cards, and the camera quality wasn't good either. The Cardini itself wasn't great either, it looked like you just learned it and immediately filmed it.
If you are planning on filming it again, make sure you have the least amount of cover on the change, along with filming it from either a top angle, or having the deck face the camera, like this.
that's more like a 1 card pass....
and that's a horrible angle....
try again with a better angle... and practice getting smoother...
though as many have said it's not the "cardini" change...
watch the tutorial where you've learned it again and make sure you have the correct hand positioning..
Practice before you upload something. and as many have stated, fix your angles. But you could do it better then me when I was a beginner so just keep trying
