first of all, you have some killer reverb there...it was kinda distracting
also, it would be nice if you would post a pdf of the score, more people would review it if they could follow along
anyway, about the music
:20 i think the chords were a bit jarring, banging on the high notes, same with the ones at :50, :58, especially with the style you are writing in
at 1:39 and teh passage from 2:14-2:25 ish was superb, awesome stuff there
the repeat just came, good, nice use of sonata form (i think...i suck with form lol)
3:23 again, the high notes are jarring, but now that i think about it, it could just be all the reverb
the ending was good too, beety-like with a nice touch with the high notes
some things that bothered me were the rhythms and teh running scales. it seemed like anytime you had some kind of theme, it was just up and down the scale. the rhythm was a bit boring, mainly because it was like a barrage never ending 16th notes. just not my kind of style.
overall though, i did enjoy this work, and i would be curious to hear it again with teh score in front of me. you made excellent use of the range of the piano, and your chords phrases and the likes seemed to work out great.
btw, can you play this? tremedous dexterity is needed it seems
good job man, i hope to hear more from you soon
