This is quite impressive for just four hours!
The piece has an interesting structure too, which I appreciate (naturally, along with the pretty melodies). As I already told you, I like the left hand arrangement, along with the variations in it. My favorite part of it is 1:28 - 1:44 :)
Maybe one day, when I decide not to be lazy (no promises), I'll cover one of your piano solo's by actually playing it (and rearranging it) on the piano. We shall see! (Will probably take a while too, since I do so many things on a whim).
Nice job!
