Naruto, One Piece, Fairytail: Reanimation

This is my contest entry for FMP's anime drawing contest of the Shounen Big 3: Naruto, One Piece, and Fairytail. Currently I am unfamiliar with both One Piece and Fairytail, so I found this contest a bit challenging haha. I actually had to study and find some things out about the characters lol. I spent some time watching anime openings and figuring out who were the heros and villians (which is much harder than it sounds haha, most characters dont follow their stereotypes. for example Gaara ends up turning good) but in the end I found some deceased villains (Zancrow and Crocodile) and decided to bring them back with Kabuto's Reanimation Jutsu. Since I was using villains in my entry, I wanted to give a dark feeling to the composition and hopefully that feeling comes across. I hope you guys like it...! Critiques would be highly appreciated. thank you.
