Some of the poses are too generic to identify with a particular show in my opinion. For example, I remember there is at least one mahou shoujo series that the heroine has a move using that heart-shaped hand gesture. Maybe Shugo Chara, I'm not sure. And if I want to do one with Houtarou, I'd compare with his thinking pose--the hair touching gesture with Yuuta when he was in front of the mirror.
Edit: Got beaten by Sound of Azure by 8 minutes.
