Elfen Lied, a great manga.
I'd say your inspiration was brought on by good things. IF anything you've not let down the inspiration for sure. Wonderful work on this as far as piano goes. As always i'm listening to this as i review, i feel if you added some strings into this that the song would shine a bit more also. Perhaps a soft rock type percussion. However all in all its a good listen. Keep it up for sure!
