Very interesting to hear your early works; it's noticeably different. I can see you were already experimenting with polyrhythms at this point (2 vs. 3). I've always admired your sense of harmony and this time is no different. Your chords are very interesting and suit your tonal melody line quite well.
35-37 were the only measures that stood out to me as a little awkward. Combining G5 with F7 (F13) with that rhythm was just weird to me, that's all.
You have a commanding sense of how chords work! I was admittedly a little bit off put by the 9th VI chords with fermatas, they just seemed like awkward pauses. You never seem to give the bass voices a break do you, haha.
Also maybe I just randomly lost my sense of pitch, but the A' section seems to be in Eb minor... different from the G minor key signature you had. Everything else is right...?
Anyway, very nice to listen to!
You seem to revolve around the tonic a lot in your A section. Prog rock has a tendency to want to gravitate there, mostly because all the notes are synonymous with a major III chord. Your melody line has a lot of potential for variations, harmonically and rhythmically, and can be used in both prime sections and new sections. Keep at it!
Interesting. It certainly sounds like a player piano type piece, good job in executing that. Would I call it jazz, per say? I think it can pass as it, but it may be a bit oversaturated by dominant 7th chords. The only note I had a problem with was the B natural at the end of m. 3, but other than that, pretty nice rendition.
