I really like the style. It looks more like a comic book than a cartoon. There is a lot of colours and colour variation on the same object so it's more complex than traditional cell shading, but it's not the "brown" of realistic graphics either. It looks very pretty and artistic without being wierd and artsy like Mad World / Epic Yarn or even Wind Waker. I also <3 water colour and impressionist paintings so the water colour effects are very cool.
