Haven't read everyone's feedback, sorry if I echo someone else.
For one, if you're going to edit your piece and post the updates, make sure you edit your original post letting us know you did that. I didn't click every new version you gave us, so you might already know this, but just in case you didn't I thought I'd mention it. I almost didn't see it 🙂
- As a pianist, it's odd for me to see sections with just one staff. Even if you only need say the treble clef, I'd still put the bass clef in with rests.
- How come you have 2 notes playing in the flute at times (or maybe other winds)? I don't recall a single moment when you gave us wind harmonies, why not just have the flute and oboe play together. I feel like it was a wasted opportunity to not hear some ideas with the instruments blended. With the type of piece this is, I'd think having solo wind instruments would be more beneficial than whole instrument groups.
- Remember that the piano is polyphonic, and although I actually really enjoyed the mystical thin texture you gave us, there were plenty of moments that didn't really feel characteristic to the instrument. You do give us sections of both hands played at the same time, but overall it felt like I could have played the part with one hand.
- The rhythms could have used some work, especially in the long whole note sections. Would have been a good time to explore a bit of counterpoint under sustained melodic lines. Again, I felt like the winds were underutilized.
Just some random points, hopefully it helps you out a little. I really liked the language you used, and the harp-like vibes in the piano were really cool. Reminded me of traditional Japanese music. Like I said before, the sparse texture overall was VERY cool; I'm so used to people on this site cramming in a bunch of unnecessary notes in every measure of their works, and yours was a breath of fresh air. I'd love to hear any additions or edits you do with this piece in the future, I'm always a fan of hearing future versions in people's music to hear how it evolves and to see if they heeded the advice of others. There are loads of great composers here, be sure to at least consider some issues they had with your music. I've been on this site for years, and their advice has always benefitted me and I'm very grateful for it.
Good luck with your music, and thanks for sharing!
