Wolf's Rain 2
I really like the world design. It has the right mix of familiar and alien that makes for a successful alternate-Earth setting. It bares some resemblance to steampunk in its mixture of antique and futuristic technology and aesthetics, but instead of reaching back to the 19th century it takes inspiration from early 20th century Eastern Europe, a time and place I haven't seen much use of in these sorts of retro-future settings. At the same time, the architecture is extended into strange patterns and ruined fragments that at times look like something from an alien planet. It's evocative despite the weaknesses of the early digital composition.
