I'm not a pro, but piano is my primary instrument.It sounded nice, but I think my ears heard you playing the same 3 notes in the left hand during most of the first minute. Also the notes were repeating a lot a good portion of the first minute. That's not horrible, but if you cut out all those excessive repeats you may end up with an even better piece. Long pieces don't always necesssarily mean better pieces.Also, was it me or did it seem you lost control of keeping the two hands apart around the interval of 1:45 and 2:05? My ears aren't the best, so....Also, what effect have you added to the video? It doesn't sound very acoustic to me.But good job though! Excellent even! I can't do the same. Well, maybe I could, but it wouldn't sound very ordened like your piece (and most classical pieces) do(es).
