The art style is so unique, for lack of a better phrase I too must say "like nothing I have ever seen before." The ending where she journeys back to the moon is really powerful. They tricked me into thinking that she was going to escape with the boy she used to play with in the long day dream sequence.
I'm not big on gen 7, but did you know that Celesteela is based on the Princess Kaguya of folktale? GF incorporated design elements from bamboo stalks as well as the space craft Kaguya to show the relationship to the moon.
Great taste? Me? *blushes* Why, thank you. I think you do too.
