You should definitely stick with it. Yes there was lots of pitchiness throughout, but there were also some very pretty moments.
One thing I noticed, on the diction end, is that you tend to swallow the beginning consonants of words, which makes it very difficult to understand what you're saying. It almost sounds as though you didn't want to end one note before you started another on the same picth because it was a crutch --- i.e., you're already singing that note, so you wouldn't have to start it again. As an example, instead of singing:
"She's a good girl, loves her mama."
You kind of sang:
"She's a goodnnnngirl, loves her mama"
It was the same on "I'm a bad boy." It was more:
"I'm a badnnnnboy."
Anyway, like I said, you should stick with it. You just sound very much like someone who's inexperienced with it right now. It sounds tentative, shy, and nervous. Like I said, though, there were certain notes that sounded very nice, so the potential is there for sure. The more you practice, the more confidence you'll gain. The more confidence you gain, the more you'll practice (hopefully). Good luck with it.
