The material itself is fantastic, but some of the sounds don't really do justice to it.
The arco strings have a sort of sucking effect on all of the transitions, which makes me feel that you are not using actual legato patches? if so I'd recommend maybe playing around with how much the notes overlap each other, and the release values on the envelopes for those sounds to get them sounding smoother (just some quick ideas I felt might help)
Good work!
