Actually, I disagree with Daniel (hey, that's my name, too... must be a genius thing...):
I like the ending with the high notes. The song is not dreary or anything, but it is definitely not a whimsical song. The last two notes left a smile
of amusement on my face--though agreeably it is aurally a little off the usual, it idea is incontrovertibly effective.
Overall I liked it; I really don’t have much to say, piano is not my expertise.
And being a newbie myself, I appreciate how long it can take for someone to reply!
