Really great.
It's spelled waltz, you may want to fix that however. In case you don't know how to fix it, just go to My Account> Audio Submissions, and click Edit.
On for my review of the music, it was great, being my main impression. Sounds almost exactly like a song from a pokemon game, if only you had it in 8-bit sound. :P The harmonics really are great. The only downside is that it feels like a theme and variations piece. The mood never really changes, and that could be bringing down the piece. In classical music, there's generally a B theme that contrasts with the A theme by being in a different key and being in a different mood. Normally when I write in a major key, I tend to write the B section in minor. That way it is like a good novel. It can't be happy the entire way through. There's got to be a "bad guy", or some problematic situation at some point so that the lead character can overcome it.At the end you should probably re-enter the A section, with the original melody in the original key, and that's pretty much all my suggestions.
The orchestration is absolutely ingenious, so I can't really give all too much information on that.
Great job. I'd be honored if you came to my page and checked out some of my stuff.
