Unless the housing's a lot denser than it looks (higher, for one thing), those streets and plazas seem to be way too big. Retail & restaurants completely detach

Unless the housing's a lot denser than it looks (higher, for one thing), those streets and plazas seem to be way too big. Retail & restaurants completely detached from housing is also questionable, if you're going for walkability. Farther apart you put things, less walkable/bikable they are, so the harder it is for businesses to be viable without public transit or (more probably) car traffic.
