|The cover in question|
(Mojo Jojo, to be exact, who's pretty much just a massive Asian stereotype, but no one really wants to tackle that issue.)
My first thought upon seeing it? "Cute." Nothing more, nothing less. The proportions of their bodies don't feel overly exaggerated (ok, aside from the eyes/heads - but that's a long time anime trope), and the poses seem innocent enough. Based on the art itself, I don't immediately think, "not for kids."
Not liking the style is a whole 'nother matter. I'm personally not a huge fan of anime, as I find the big eye thing kinda creepy. However, I can also recognize talent, even in styles I'm not overly fond of.
You can take some task with aging the girls, but is it inherently wrong to imagine that Blossom, Bubbles and Buttercup might grow older, and continue to be heroic? That seems like a pretty empowering thought, to me. Which goes along with Dirk Woods' response:
I think they were thinking of it more along the lines of “female empowerment” than the kind of thing you guys are talking about, but certainly, we’re sensitive to the issues here.
Take the fan art to the right, it's the same concept, The Powerpuff Girls grown up, and the style is far more realistic, clearly using models to set the poses. It also strikes me as much more sexualized than what Yoon created. All supermodel bulging boobs and hitched hips.
Of course, that's fan art and not official IDW/Cartoon Network material. It is a difference. And there's FAR, FAR worse fan art out there...believe me.
It is a matter of perception, I admit. With such a personal thing like sexuality and eroticism, it always is. Some people are into babyism, different strokes, folks.
When Dennis Barger looks at Mimi Yoon's art he sees sex. I see three heroic teenage girls. His interpretation of them wearing "rubber fetish wear" is also not the first thing that came to my head, either (looks like a pretty standard, anime-influenced, "superhero" costumes based on the outfits from the show).
I honestly can't help wondering if that says more about him than the art itself.
And now, of course, IDW and Cartoon Network have pulled the cover.
