Hi Demetrio.
First, let me say that your works has a good potential, both expressive and musical, in it.
Other here can be more qualified and exhaustive, still I wish to share with you my impressionistic thoughts about your submission.
Then, speaking from a listener’s point of view, it deserves more moulding to wield it out.
I feel a lack of contrast in dynamics and timbre — eg. the tune that drives 1st movement in canon form, moves between instruments whose sound is very similar, at least they play in a range that make them sound very similar to each other (cello, viola, bassoon, clarinet in its lower range etc).
I suggest you to experiment a wider palette of pitches and colors, avoiding a VSL catalogue effect, of course.
This will also help to pass the vibe that it takes a lot to build up to a point I feel at the moment.
What about reshaping it into a three movement set?
I hear the “spirit”, not necessarily the actual music, of this one 1st movement a good foundation for a middle one.
This piece can turn into an interesting work for chamber orchestra. Don’t give it up!
Thank you for sharing.
EDIT. The more I listen to it, the more I enjoy it. Especially here, where both movements are linked into one track.
