I love the natural framing caused by the green door way, its a nice touch.
I might have upped the contrast some more in editing, the picture comes off a little flat. The lack of window makes it hard to. I feel like it meets the challenge because it is of a store, but the description does explicitly ask for windows in some way.
I almost called this DNMC for being shot through a door instead of a window, then I realized the front of the display case is a window. Kudos for a somewhat sneaky take on the topic. There's a modest amount of fisheye distortion visible, which can be corrected for under advanced rules.
I like the way you included a bit of the door frame for context. I think this could have been a good chance to get more of a pose from the shopkeep. Bring a bit of emotion to the photo.
