I'm a huge Natsume Yuujinchou fan, that's not a secret, and I certainly loved all of the previous season, with a slight downer on the second one. This seem to follow the first and third seasons' example, being absolutely adorable and wonderful. Natsume has changed since the first season as a person and I really did notice that as I watched this first episode.
The style has no difference from before, however, I guess it grew on me. I first thought it looked a bit odd - especially the eyelashes - but now I don't even notice that. Otherwise the style is shoujo, but it doesn't look ridiculous with huge eyes or anything.
The story is as much fantasy as before, still being quite down-to-earth and it'd seem the concept is the same; it deals with relationship between humans, demon, and humans and demons. The characters drive the story forward, just as before, and it seem to keep it's quite light-heartedness.
