It is a lovely shot (aside from the fact that I have a Laurel Burch mug just like this one). The paper appears to be sepia-toned --- just a play of light, or did you add the sepia?
I like this... the sharpness and focus and color, and that I can't see where the light comes from, but it's effect. Surely does feel of morning, as much from objects as light ;-).
