I just saw this on io9, and it looks great. Lantern City is a new comic coming soon, with a free preview at that link. Its overall aesthetic seems very much like how I see Spire City: steampunk as seen from below, mired deep in the amazing new technologies of the factories, but divorced from the sense of wonder afforded to those in high society. I'm not a frequent comic reader, but this looks very cool, very worth checking out.
Also check out this interview with the creators of the series. Looks like there's a big vision behind this series, well beyond only a single run of comics: a novel, a TV show, and maybe more.
