I know what erose86 is saying, but I quite like the fact that it's only one fret in focus, kinda showing you where the finger goes (in a crude way I know).
I like it as a picture and I like it as a piece of art.
I agree that the in focus area should be in the top third.
People do tend to start at one of the upper corners when viewing a photo but they still perceive a photo as they would viewing real life.
The in focus area constitutes a full stop and having it closer to your feet than the perceived other end of the photo makes the shot seem a bit claustrophobic.
