While I like your variety of voices in this current demo, you don't need to say exactly what role you're attempting to do every single time, as it unnecessarily extends the demo reel's length(which to a considerable amount of people, can end up being generally exhausting to get through). Just leave the audience themselves to guess what exactly they're listening to the next time you make a demo reel, and I guarantee that you'll have the chance of seeing more users willing to leave a critique on your work.

And this is a personal quibble of mine, but I feel adding some more enthusiasm into your various performances(when appropriate), will help make the characters feel that much more alive and interesting to listen to, for many people.

But for a first attempt, this was quite good. And on the bright side, you can only get better from here.

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.
