Well...
Firstly, its very different from the original, though it still holds the essential theme its a very different kind of song from the original one and achieves a very different effect.
But thats not a bad thing youv added alot to it and its enjoyable to listen to and it makes an interesting variation, though since you have distanced it from the original so much its not as good. (not that any remix could match the work of Michiko Naruke).
but yea, overall an interesting piece of work.
