This picture seems a bit un-inspired. Would have been more interesting if the perspective would have been altered, rather than a normal view (how your eye see's it). Perhaps find something to be the focus on this gorgeous letter box.
Possibly the coolest mailbox I have seen in a long time. Other than that, this photo doesn't carry a lot of interest. Maybe playing around with depth of field, angles, or something to make it more dramatic could have helped.
