Great style
Your animation elements were damn good... The wind ruffling clothing, blowing waves of grass, and down to all the details of everything that is supposed to move. And that's the problem with most anime, the lack of movement in passive scenes. But you covered it tottally. The drawings were alright, could have been better, but the animation truly made the drawings bloom. I was a little confused about the sudden sprouting of wings, it could have been more in depth before bringing that up, but I guess it went along with the music.
Nice Job!
