I agree that these villages are not extremely realistic (post), but for different reasons. My goal was to generate "interesting" maps, as a result some details on the same map can be more appropriate for towns, others - for villages.
The things you mention as wrong make me think you imagine something like a bunch of houses connected by a spaghetti of trails tightly packed within a small area? Maybe some early villages looked like that, Vikings or something. Not sure as it's not my period. I am more familiar with medieval settlements and they were my reference, although modern villages are not much different. A typical small village looked like a crossroads with important buildings (a church, an inn, a manor house, a mill) either at the center, or at the end of those roads. The streets didn't need to be exactly "planned" (although some villages and towns were actually planned, it was not that rare) to be perpendicular - it's a quite natural layout, especially if houses are backed by crofts.
