July 18, 200917 yr While a lot of that sounds amazing the score is simply a maze. (LOLZ) I just want to comment on this latter aspect right now: Finding ones way through those repeat signs, endings, da capos and all that takes quite an effort on its own and is in no way contributive to the legibility of your piece. The first 5 measures that come again and again are really not long enough to justify so much jumping around. Just copy/paste them to wherever they appear and make it one continuous score, which will make the score a bit longer but a lot easier to read. This -especially- applies for the da Capo, since in a da Capo it is rather customary to leave out repetitions in the first place. Your midi indicates however that you -do- want the repetitions also in the da Capo. All this would be a lot clearer in a continuous score without repeat signs. (Of course, the other question is whether your piece actually needs so many repetitions, but that's a different thing.)
July 18, 200917 yr Oh, one more thing that just jumped into my eye: The rhythm in measure 29 is a real pain to read. At least notate it like this: But far better, something like the following, which is not -exactly- the same rhythm you wrote, but in that tempo the difference will be marginal and it's much more comfortable to read: (16th, like notated here, are slightly slower than your duplet 32nds, which are the same as dotted ordinary 32nds. You could of course also write ordinary 32nds and "err" in the other direction.)
