Hey Janet great job, I really like the piano lines.
Just throwing some ideas out to make it more epic sounding (if thats what you want). Around the 40 second mark to 50 seconds I would double the quiet bass part with a male "AHH" choir (Baritones) at a PP dynamic then ramp it up a little and start adding a little higher octaves with the bass part. It would really fill it out. Make sure to use lots of verb or surround mics if you have them, for the quiet choir part.
Also, some of the violin lines sound like you are just playing the chords on your keyboard, but with a violin sound. I know your a very good pianist, I think playing each part/line in separately, and adding a little variation or voice leading on the higher notes will go a long way.
Those are thoughts of the top of my head, you can take them or leave them, I really liked the piece. Great job!
