The Japanese themed houses are very well made, and are definitely my favorite of the bunch. They are also the only area that actually had paths/walkways among the houses, and likewise the only area that felt to me like an actual neighborhood, rather than a jigsaw puzzle of houses.

Mind you, the other areas are not awful, but they feel very artificial, especially the modern one. The modern and cabin area need big trees to break up the monotony, like the fantasy area has. It's a pity SL doesn't support megaprims.
