Yeah, that's a great image. In my opinion, it would be slightly improved if some of the original fog was drifting in front of/around the towers of the city, as this would both be a nice callback to the original art and help show that the future is still somewhat unclear, but the effort involved might be incommensurate with the results.
I would love to have a digital artist draw something very much like my mashup (but incorporating your suggestion) as an original composition, so I could use it.
