it's a beautiful touch, but I do think it is in fact too slow.. I know you want to show more emotion by playing like this, but in fact, it'd work in your favour to play it a bit faster and with more movement ~ you'd do him justice to play it more strictly, actually..
this, along with June, is my favourite of the Tchai seasons, and I've always loved Tchai ~ you seem to enjoy this work too, and may get more out of it to play it differently
nice job though
