musically, interesting.
notationally, a disaster.
I'm gonna be a total bitch here, but you know already how much I admire your musical abilities, so I'll just nit-pick at your notational abilities instead
you over-use double dotted values. they bring nothing but confusion. replace them in the score with normal non-dotted and tied or single dotted and tied values where applicable.
when a score is in C, always add an indication on the first page (Gardner Read).
first page of a score SHOULD contain one line of every instrument playing in the piece. ie: if you have full woodwinds, brass and strings, the first system should include staves for all of those, even if they are empty.
personally, I don't find that beaming across barlines brings anything to the notational clarity, but I guess that's a personal choice. I find it more unattractive than anything else.
there are some collisions between indications and notational elements (like the "à2" colliding with rests, hairpins colliding with slurs and staves, etc...)
why is there an entire measure rest at the end?
I think you could have gone with a slightly smaller staff size to give a looser fit to the music. It's just a bit too stuffy and congested. It needs a bit more blank space.
Which is, of course, not a comment on the music.
It really is a wonderful piece. A bit more modern than what I personally enjoy listening to, but well worth the effort. It's beautifully concise writing, and quite colourful use of the orchestra. I mean, just how much can I say that isn't just belaboring the point that this IS a great piece of music. You should rightfully be proud of what you have achieved here.
