Thanks for the video, Jamie!
Good for you..... I don't think I'd ever be able to play piano with a sweatshirt suffocating my wrists like that, so I must say congratulations.
Hey, for 4 hours, I must say you really have most of it under your belt. Obviously, it is still early and you seem a little hesitant and cautious, but the control is there (something I can't say about my own playing), and that is most important. Without that control, your accomplishment in the piece in the future is bottle-necked because of not getting the elementary stuff taken care of (what happens to me most of the time). This is not a problem for you I can see, so I really don't have anything bad to say.
It would be great if you could maybe spend another 4 hours (

or longer) practicing it and make another video so we can see how the finished version emerged from this early stage.
