Yes, you... You know that I never adjusted to your name change ;).
Okay, about YouTube - specifically, your cover of "Let It Go".
This song in particular has a flowing problem, such as I mentioned in chat. Try enunciating each word more clearly. While flowing smoothly from one word to the next is not a bad thing, it shouldn't come at the expense of clarity. It also sounds more... artificial when you flow it more.
Some things you did with this song threw me - you changed the tune up a bit from what's in the movie. What this intentional? I'm not a huge fan of changing things around like that, but I know that some people like it, so if it was intentional that's fine.
This song could, like, really use some background music. It'll enhance the listening experience. If you sing along with music in your ears while recording, it should probably also help with some of the shakiness.
4.) Don't sing with a cold.
...not much to elaborate on here, I think that's pretty clear by itself ;)
