Straighten out the horizon of the photo, and get a bit more light on the glass (CHATELLE is a little hard to read), and you might have a contending photo for this challenge. I like the effect you've produce with warm versus cold.
A bit of a white balance problem here, the backlight (natural light) is really blue and the frontlight is yellowish, I think this whitebalance contrast makes this shot look like a snapshot. I would rather go with all natural light or all tungsten light and set the white balance setting right on your camera if possible. The image does not show how cold it is out side either. Would love a sip of that though....
