I'm currently working on the Gideon tileset (hope, it'll be finished in the end of next week). So, it could be used for Stormhold as well. I try to keep the style close both to Imperial an Ayleidic, though adding some unique details. I see Gideon as a grim, dark and gloomy and at the same time majestic and dignified city. Numerous channels are crossing its streets and the lanterns make the surrounding night even darker... An example of Gideon house: http://i626.photobucket.com/albums/tt346/rhymer1987/001.jpg
