What you are doing is card artistry. It is an art form that is meant to look beautiful, so in spite of saying what everyone else has already said, I'm going to tell you to slow it down. On top of that you can add style. Don't treat a move you learn as it is set in stone. Incorporate and add on to flourishes. Developing a style in Cardistry is what separates the amateurs from the professionals. Above all else, just keep practicing and good luck!
