Great piece! The waltz movement reminds me of "La Valse" by Ravel and the last movement gives me Leonard Bernstein vibes. I wish I had more time to look at the score in detail to maybe give more critical feedback - from what little I've seen though I have to ask whether the enharmonics that you've used in the harp part are really streamlined to help the harp player most easily play the part? Great job though - I enjoyed it thoroughly!
