Maybe it's just me, but you seem to use 7/4 time in a very natural, lyrical way. Usually this tempo sticks out like a sore thumb for me, but I don't think I would have even noticed if I wasn't looking at the score. Interesting.
I like the way that the previous piece hinted at the maestoso here. In the piece before this one, there was this short climax at its grandiose theme, but here, it's like it gets a chance to be further elaborated on in this "remix" of all the previous pieces that came before it. It's a satisfying climax! And the ending C Major chord is also really satisfying and feels truly "final." (I think my favorite part are the 2 bars labelled martellato soon after the quasi cadenza, those chords are positively delicious!)
I'm looking for things to critique, but I just don't see anything to criticize, personally. I just really like this suite, and your way of writing. What can I say? I'm sure your growth as a composer will come naturally with more writing, anyway, as all composers do. I hope at some point you can get a live recording of this music, because the only thing holding it back is the MIDI performance.
Thanks for sharing with us! :D
