|Greetings from the Critique Club!
Meeting the Challenge: I think this is probably the biggest driving factor in your 4.x score. I suspect that people wanted to see sheet metal in this challenge, and I'm afraid you probably got those 19 3's, 6 2's, and 7 1's simple because of a lack of sheet metal.. With that being said, I personally do like the OOB approach to the subject.
Composition: The composition is decent. I say decent because while you did include a leading line (the light poles), your title emphasises the weather conditions, I would have really liked this taken just a few inches from the pavement, to emphasize the reflections of the wet pavement (probably the most interesting aspect of this photograph, even composed as it is..). I also feel there is an issue with useless dark space to the right of the composition.
Technical Quality: Nothing to really complain about here, the photograph is sharp and technically competent..
Creativity: High points for you here. Certainly a creative approach to this challenge.
Conclusion: This is an interesting "coffee shop" photograph. I think it offers the viewer an interesting scene that invites exploration. I do think there are a few things that could have been improved, but this isn't bad considering the situation you were in.
