Short and simple, yet beautifully tranquil. I wouldn't call it a waltz as much as I would an effectively soothing lullaby.

You've most likely heard this before(I know I have), this piece could be longer, as it has a lot of potential, and it could be built upon, if you so desired to do so.

In the meantime, good work, I look forward to hearing more.

Awesome, This song is creepy, Yet so beautiful,

Nice job on this song. I give praise to you good sir.

Pretty

This has a lot of potential, if you wanted it to be a waltz. Right now, to me at least, it sounds like a musicbox that someone is listening to, reminiscing on dancing with the demon. Still, good job.

Pwetty

And I agreez with Ethnul1, this could be longer..
Still very pretty :D

Huzzah!

This is great. It has a mood that I could really use in a cartoon. Great job. :D
