I think it's great, too. I never thought I'd like such a style... it's amazing that the artist can make Fuu look so cute and girly and have Mugen be so rough and crude at the same time, without them seeming completely foreign to each other. haha
Holy crap... definitely a lot easier to get a sinsibility of how you work by looking at the un-colored or inked pieces. I really love the jagged edges where the shadows meet light here. Not to mention, his pointy little nose and huge, stretched out feet are pretty neat super-stylized additions as well.
