Great timing. I liked the opposing direction of movement between what I picked up as the two main subjects here - the woman and the sign in the window. Both her feet being entirely in the frame, would have been better though.
Love the idea - Just think the composition needs a bit of work - The woman is too centered and the lack of her foot is a little distracting. This I think could have worked really well if a person was in the area of the doorway walking with a bit more movement. Maybe a tighter crop off the top would also keep us focused on the subject matter - Great idea though.
