7 from me. Love the negative space and the sharp face. Not the sensor dust though, but no points off for that... I have dust bunnies galore, but I usually fix them in Advanced.
I know the rule of thirds, and I know it's better for the subject to be entering the scene rather than leaving it. The close-up macro of the fly is excellent, I'm hoping to do as well with my new lenses on order. I personally think this is exaggerated, meaning too far from that vertical third line. I could be wrong, I interpret the rule of thirds as the place to center the subject, and it looks like you've placed your subject completely within the top-right third box. I still give this a 6 for clarity, detail, and deep rich colors.
