I've been waiting for a score to be posted, but there still isn't one, although I can assume what the score would look like.
First, the "young" in "young composers music forum" means "young" as in "new to composing" rather than "young in age." I don't think that you, at 54, are as old as you think you are on this site.
You said your goal was to write music that satisfies your musical sensibility. If you have done that, then you have accomplished your goal.
Based on what you said and what I hear in this piece, it seems to be a bunch of random notes hammered out. There is nothing wrong with that, but it doesn't leave any room for comment, which is probably why no one has responded yet until my post. If you wanted to write music based on plunking down random notes, you seemed to have already mastered the technique, so there isn't much else to say.
If you want to be more musical, as you say you do, you need to either learn the techniques of composition, or learn how to use your program. Music isn't limited to writing notes on paper, and people have very sucessful compositions using musical programs and don't know a thing about notation. But, to be harsh here, it sounds like you don't understand either.
You said you have written 97 more of these things? And that instead of polishing one piece, you get bored with it and start another? Certainly this isn't out of the ordinary for a young composer (heck, I had a catalogue of 157 pieces before I hunkered down and got serious with composition, but those pieces are in a vault somewhere and no one will ever know about them), but when are you going to start putting quality before quantity and share those compositions, too?
There is something to be said about aleatoric music ("random" or "chance" music) but even within that genre, there is still technique and sophistication behind the music.
I am sure this piece actually is playable by a human, as I have heard music played that sounded like the performer had 5 hands and was much more chaotic sounding than your piece.
Not sure what else to say...
