The RHS leads really well towards the subject, whereas I feel that the boy's great expression and placement in the frame is competing with the bright ridge in the middle of the collar and bright top LH corner/side. I feel it would be more cohesive and superb if these two areas were burned in sympathetically.
Thanks for the comments. Baxter, I should have mentioned that this is not a final print; in the final image, both areas you mentioned will be knocked down appropriately. I wish I could always post from a scanned final image, however, too frequently the finished size is too large to scan.
