it looks okay but Im not sure if its original. there are several displays like this :
damn straight by Kev Ho
Tudor cut by um, Tudor
however your version looks easier for smaller hands. still not very good tutorial quality unfortunately, which is probably why rich didn't put it in the media section.
instead of making a big deal over this one move, and making a video JUST for a tutorial, why not invent a whole BUNCH of these moves, then shoot a video comprising ALL your original material? then if anything looks cool enough for people to care they will ask for a tutorial, and then you can put one up.
