Hello! Nice sounding piece you got here, and I enjoyed listening.
Did you mean to not write for cello in treble clef at all? I feel because this is a cello feature, utilizing the instrument’s whole range is important and you can do so so much more with the instrument than you did. It feels so tame in what it is playing at all times, and it can go wild with double stops and timbre!
I feel the same about the orchestra accompaniment, but less so. Because it is a concerto, I give the pass for the orchestra part being tamed out a bit, but it should be each instrument, the orchestra and the cello, bouncing off of each other in magical ways.
Overall, I notice the music just stops sometimes and then you start a new section. This is jarring for some of them, and a cool effect for others, but I think working on transitions could elevate the flow of your music.
Again, I enjoyed listening through! The midi was nice, there were cool chords, and I listened to the end. The rhythms, range, feeling, dynamics, etc. can all be so much more drastic, but that is what we are all working towards as composers.
Thanks for sharing,
Evan
