I check the 1st mov only, I come back later...
WOW, this is the very best piece I've seen for you, the great effort is quite clear to me, very mature structure and development, I heard a post-beethoven, a bit of post-brahms, but mainly prokofiev and scriabin, (debussy was the great absent there :D but one can't have it all)
Either you can't play your own sonata, or, you lied when you told me my Hummingbird is too difficult for you :laugh: this is more difficult that all my student pieces together !
I don't know how much took you to write this but is a fine job.
I'm not very sure about the soft part before ending the 1st mov, sounded to me a little out of place, or like an unnecessary coda.
To check the playability and how comfortable is your piano writing I would have to print it and play it, well, study it and play it because is not very easy, I can't do it now but within the future remind me to print this, is very nice. I'll come back to check the other movs.
Sincere Congrats Zach :thumbsup:
