Here's a link to my piece:

I appreciate feedback.
Technically what's happening: The piece is in 5/4, which gives space to the melodic lines, key of E flat, playing with G natural and flat. It starts with piano ostinato, adds a cello ostinato, successively adds 2 melodies and then combines the 2 melodies over the ostinatos.
I created it using mixcraft pro studio 8 virtual instruments. Feedback on another website was to the effect that real strings on long notes have more dynamics. Do you agree or do you think the more flat, even strings works better?
