I like the idea a lot, and you're fan art skills are getting better. As for the characters, I think Konan looks pretty good, but Naruto, and Pain look a little bit off to me. With Pain, it's mainly the shape of his face. It's not bad, but for some reason I don't like it. Sorry, it's kind of hard for me to explain. As for Naruto, it's mainly the position he's in. In Taekwondo, a martial art from Korea, they call that position a "horse stance." I guess it's because I've grown accustomed to only seeing people, kick, punch, or block in that position. Seeing Naruto with his arms folded in that position, it just looks awkward to me. Of course this is only my personal perspective, and some may see it differently. Well, I hope you didn't mind my criticism's this time, and keep up the good work.
