I think I really like the way you use the piano here (and something like bell playing along with it too?) It's conveying the picture of the song title....containing both happy and sad melody. What soundfont do you use? It sounds really clear and powerful. :)
I only hope that the heavy metal part will sync well with this.
Well most likely i will cut a lot of this out to add the HM intro to give it more of an "Edgey" feeling.
Please contact me if you would like to use this in a project. We can discuss the details.
