You went a little too much with this rendition. The original rendition was very quiet and graceful. I was a little disappointed by this very bombastic approach. Hotaru is a very shy and timid girl. Someone who's face would get flustered if a boy were to show even a hint of affection. Her music should really capture this innocent aspect of her personality.
Please contact me if you would like to use this in a project. We can discuss the details.
