Very nice job! I'm impressed by how much detail is put into this. One of the things that stands out in that regard, awkwardness of the note aside, I'm impressed by the detail and imperfections in the nipples/areolae.
Great looking bust! =] Do you push in the sockets and close the eyelids around them when you sculpt, or do you resculpt part of the face when you add the spheres for the eyes? Also, have you ever considered putting up a timelapse of your sculpting process? I'd certainly buy it if you had a gnomon/eat3d - like dvd!
