An interesting piece, Rob. I think the mass of white all around tends to overpower it. You might try removing most white from the left side. It will still be total high key, but give the subject greater dominance.
My personal opinion is just about the opposite of Doug's and typically I agree with everything he says. I have no problem at all with the negative space. And I really like the included shadow and wood texture. About the only thing I would change would be to remove the two small patches of texture in the upper right.
It's really interesting reading the comments above mine. I see words like creative, awesome, finest and unusual. No real negatives. Have you ever had a Caedes friend say that your work suct?
greater dominance.
