An anime neighborhood (small town or suburb, not a city, no skyscrapers). Btw, it's something we see all the time in a "Slice of Life" genre. Please, build blocks, not single housing units (difficult to kitbash). A good use-case scenario would be, obviously, anime! Also, having an NPR render for one of KB3D's portfolios would stand out.
More tips: go for a general look and don't make it heavily themed in a typical way (e.g. School, Shinto Shrines). Rooftops (variety) are important for top-down or landscapes. (but "streets" aren't that useful, give us backgrounds instead)
