This is one of my favorite songs from Kirby and the Crystal Shards... I don't know if slowing the song down was necessarily the best creative choice. In doing so you were able to change up the melody slightly, but what made this song great from the game was the upbeat exciting feel. Slowing it down kind of took the "umph" out of it.
I also noticed that beyond a few creative twists on the melody, there really wasn't much "Remixed" in this song.
I just feel a little underwhelmed. But don't give up on music! Improvement comes from criticism and strength comes from your ability to take such criticism. I have no doubt one day you may wow me ^_^
