The image meets the subject matter dead on. A sound demonstration of the creative process in meeting the challenge in a very unusual way. A couple of minor detail problems as the image appears to be over sharpened, but that may be a lighting artifact. The DOF could have been used more effectively. A good solid entry into the challenge.
I'm not sure, but I think my eye wants the focus on the pencil tips and it's disconcerting having to find the focus...which is on the wood. Nice composition however.
