I really liked the piano writing here. Some passages remind me of Mozarts's Don Giovanni - and I mean that as a compliment. There were times, though when the orchestra part didn't quite work for me - not quite sure why. Radical thought: would this work as a solo piano work? I think the ideas are compelling, and the piano writing is so well handled, that it could be done. Anyway, please take this a constructive thought - and feel free to toss it in the trash. But I did want to register my 2 cents.
