This is a masterpiece. My very first thought was " Studio Ghibli is on Newgrounds". Everything is great about this movie: animation, art style, music, story. Only negative point for me is that the art style is maybe too close to the original and some parts, especially the trees, look like they are copypasted from Nausica. I don't know exactly if this is a sign for your perfectionism or a lack of originality. Anyways, I can respect a good forger as much as I rrespect the original. Great job overall! :)
