I love the irony of this photo, and its great how you included the "open 7 days" wording. I enjoy the angle and the expression of the man, however I think your horizon is slightly off.
Very nice. I run a frame shop too. It can definitely be very busy. Anyway, the focus is a little soft on this one, and I think that the dark door frame to the left of the photo is distracting. Perhaps open doors would have made a better composition.
