Nice! The flutes definitely give it that 'foe from the winds' vibe that I imagined with the character. I envision quite a gentle boss-fight with this, maybe some form of introduction.
Now I want more.. I wish the song was a bit longer, with some variation on the theme perhaps. Maybe a more bossy part. I feel like that could work well.
Overall, well done! (oh, and that art rocks! Made it yourself?)
