This is a pose from an anime character. Naruto/Itachi Rebel Girl gave me a list of some good reading if you want to learn about anime and read some good examples:
1. The Sasuke brothers
2. The Adventures of Shark Boy and Lava Girl
3. Innocent Heart
4. Demonic Blood
Naruto/Itachi Rebel Girl is a self-confessed Naruto Freak and hopes to be an anime artist and author. She already has several notebooks filled with ideas and sketches. You go, Naruto/Itachi Rebel girl!
