Very classy arrangement! As to publishing it, I wish you luck! I, myself, made a piano solo arrangement of Rachmaninoff's Eighteenth Variation in 1997 (to my knowledge, the first which was "faithful" to the piano/orchestra original) and it has been downloaded thousands of times from the Internet. I never intended to sell it, but to share it. A few years after I uploaded my arrangement (which can be found on IMSL website --- Loveridge version), another competent arranger (initials "R S") published his own version----almost identical to mine. Now, there are several arrangements which are available for free from the Internet. The sad reality is that even if you succeed in getting your work published you still have to accept that many (dishonest) players will provide free copies to others on the Internet. But, I guess SOME profit is better than none!
I also have uploaded my arrangement (actually, a "tweak" of the original) of Grieg's "Morning" (Morgenstimmung), which also is free to download on IMSL. Again, I'm not interested in profiting from it, but enjoy sharing.
Keep up the good work!
