I like the concept for this one, but the modelling and materials could use some tweaking. I'm not sure about the background either. Everything done with Blender 2.58a.
I might change it a bit if I think of something interesting to do with it -- but I'm starting to like it the way it is, even if it's a little simplistic. It'd be nice to smooth out the curves on the notes so that it looks better at high resolutions, but with the mesh curved into the S-shape now it'd be hard to fix that... I should have done that before applying the curve...
