Euphonium Concerto "Pluto" - 2nd Movement, The Elysian Fields - Original Work

First time creating a piano reduction which means it's probably bad and that's okay
This is the second movement of my upcoming Euphonium Concerto (don't ask why I started with this one, creative brains do weird things). The program notes are as follows (though very much subject to change):
"The Elysian Fields, the favored realm of the Queen of the Underworld. So too then did the King of the Underworld find reprieve in visiting. This visit was a special occassion--the last day of Winter in the mortal realms. The lovers embrace, they sing, they dance. Yet Spring called, and the Queen must bid adieu, to a King who sends her off with his best imitation of a smile. As he walks back to the palace to get back to his duties, he hums a familiar tune, only for it to break under the weight of another long half-year."
