This is my entry made on autodesk sketchbook! :D I chose the song Clair De Lune. Clair de Lune means 'moonlight' in French so you can see that moonlight ribbon. The person who composed the song (Debussy) kind of sounded like he was manipulating moonlight into a piano song so I did that. The rhythm of the song is as flowing as water so I added the river. I stood a lot of time studying hands :') (specifically mine xP)
