Your composition it is truly outstanding, very well crafted. Excellent arrangements.
Minor criticism: In earlier parts of the composition some of the articulations felt a bit short. And the reverb/ambiance sounds a little mid-range in parts (nasal) I guess that be 400 to 1k range, care is required with that, either try filter cut on the reverb or strings, maybe both, hear how it goes.
Important Tip: Sample libraries are quite accurate, so accurate that certain notes such as 'A' can resonate, therefore needs to be tamed. You can use envelopes to automate filters for any specific 'note' in the composition. Professional performers usually know their instruments very well, well enough to tame certain notes that resonate more than others.
I wish you great success!
