Fairly good in my book
Your animation was pretty good I must say. I did like the music a great deal, you did well in choosing it. The storyline you wrote was quite beautiful was well. Despite I am not one for sad endings, usually, I thought it was a beautiful ending. Though I am having the same issue as the previous reviewer, the hero was too young. Not to mention, I don't know if you are a Shaman King fan or not, but the hero reminded me of Yoh. And despite the fact I do like the serious, I maybe am getting a bit wore on the anime style. Though I can still watch it, but I do think you need to find more of a style of your own design in anime if that is what you like to draw.
