You know what, you got a good natural voice. Something memorably unique about it. I think with a little bit of time, you know, your acting improves a little bit, you play with your range more, I think you could be a seriously kickass VA. I say to get yourself out there and do auditions, it's a great trial by fire way to get practice.
Only thing is I'd tell you, take out all of the parts of the demo that are you describing the next voice type you're going to do. Ideally, folks tell me demos should be like around the one minute mark or so (I've always been bad at keeping to that myself), which you could achieve by removing you introducing the next voice and cutting down the length of the individual lines for the voice types a bit. Not a huge deal, don't worry about it though for right now hah.
But yeah, I'd say you might really have something, amigo. Keep it up. Thanks for reading.
