The audio quality is really good. If you are wanting to use this to promote yourself as a voice over narrator, or spokesperson, then this is great.
If your goal is to be an actor as well, I would recommend making a few demo reels to show different voice styles/character voices you can create, as well as a few snippets showing emotion for acting ability. Be able to show fear, nervousness, or just being quirky.
Have fun experimenting with different lines, voices, and emotions, then pick the ones you want.
However, this demo is pretty solid in my opinion. Depending on what your goal is, you should either do more of this, or expand your goals.
