Pretty good tutorial, though I won't be doing backflips anytime soon (Needed ankle surgery because of a poorly landed backflip turned me off of them...)
Anyways, just a suggestion for you and anyone making tutorials. Do the trick first before you start the actual tutorial bit! I suppose it's not as important for the basic stuff, everyone knows what a backflip looks like. But it drives me crazy when I'm looking for new moves and I can't tell what it's actually supposed to be until the very end of the tutorial. Just a thought.
