At least you know the name of the effect you're butchering. You are way too jerky and unnatural when linking the cards. You flashed, you even noticed it and you still keep the video up. I think, for me, the worst part is that you knowingly call it practice. If you are still practicing, do not put up a video. Learn some patter, and remember, this is an elegant effect when performed right. It should not be set to whatever music that was. It should not be done poorly by a kid who thinks it is perfect for the "streets"
