I'm not sure if this is good enough here. The artist always draws like this. Though I understand that some might not like it, I find it to be quite charming. Take a look at his pixiv if you're interested. http://www.pixiv.net/member.php?id=21298
And here's a pretty good video by him, http://www.nicovideo.jp/watch/sm21240810 It's Marisa vs Byakuren.

Anyone know the name for this kind of style?

I for one think it looks awesome!

I like the style. It reminds me of some of the pictures made by artists at Pixar. Not really sure what the style is called.
