You got a good natural voice. It's pretty unique and has a certain depth and character that sadly too many female VAs are kinda lacking. I'm very, very far from being a pro with any right to give even constructive criticism, so take my words here with pounds of salt. Your acting, though not the worst I've ever heard, needs improvement, but don't take remark that too harsh, the improvement very much just comes with experience and in the not too distant future you'll listen back on this and be like "Oh my god, I sounded like THAT? GROSS" hahah.
Your vocal sound has the potential to be really great for a LOT of things, but to be truthful when I heard this demo my first thought was "This would be killer in the mumblecore style." Look it up if you haven't heard of it, it's a style I really like.
I'll have my eye, well, ear on you. I'll be looking forward to your next pieces and your inevitable improvement as long as you keep with it. Have fun!
