Thanks silas. For the arpeggio bit, I tried to have the arpeggios resemble the structure of the beginning. I mostly added it because it is fun (and easy) to play it fast. =P
I had heard a little bit about that about him as a painter, pliorious. Admittedly, I didn't do much (if any) reading of analyses of the paintings but rather used them as direct inspiration. That painting you linked is great; especially the title. Maybe I should just put a watermark donkey on the sheet music haha.
