Congrats on being able to do voice acting; that's always seemed like a fun career to me. Not something I could ever do though.
Your singing is pretty good, I think you definitely have potential to do that along with voices someday, if that's something you want to do. If you're interested in honest critique though, you could probably use some work on it before singing professionally. I'm afraid I don't know enough about music to be overly helpful about how it could be better, but there are places where it sounds just a little "off" to me. That aside, it's still very good, pleasant to listen to, easily recognizable, and you really should keep at it.
