Put it into a trick, there is no point showing a change as a stand alone thing. Its not that impressive (I don't mean that in a derogatory sense, I mean I appreciate the skill etc. but doing any sleight on it's own is no way near as impressive as making it magical). Make a trick surrounding it, get some patter to go with it that will really draw the spectator in, finish with the change - I guarantee it will be more impressive.
Watching that, I think "yeah its very skilled", but I wasn't enthralled and amazed. I know people can do clever things with cards - everybody knows that - what you need to do is be a master of getting the audience interested, captivating them, then do the move - it will be a thousand times more impressive.
Also don't give a tutorial. Your magic will suffer if people can just look you up on youtube and see how you do everything!
