A mix of Amaterasu from Okami and Link (in wolf form) from Twilight Princess. As a bonus, a bit of a mix of Midna and Issun (the cape is pretty much the only part of Issun though).
I tried to give the picture the ink-brushed look that Okami had, which is why most of the lines are thick. For those who haven't played Okami, you can draw symbols (such as the moon in this case) to change things in the game. Link has his shield instead of the mirrors that Amaterasu could use.
