Also, super thanks to my friend Melody Ledford who created the brush I used to get the lighting and shadow effects. She used it on her art better than I did, but it sure did make conveying different layers of depth a whole lot easier. Check out her art at: http://sheet-music-melodies.tumblr.com/
Now to head home and get this thing into a pdf!
UPDATE: Added the file with the title and my name.
