You've got a good, chill vibe that fits Keiji well. You do have some more room to play. I'd like a little more nuance with some of the lines. My biggest thing with your audition is the volume. You're the kind of quiet that makes me wonder if you're recording in a dorm space or something like that, like there's someone right next to you you're trying not to disturb. The issue is you're really hard to hear. There's only so much I can artificially raise your volume before it starts to deteriorate. And even then, with the way you seem to be whispering, it would be instantly noticeable that you were.

Obviously, I don't know your situation so I can't tell you where to go or how to record, but I highly recommend finding a space where you can use your voice. So so many voice actors will tell you about the closet they started in. I've used college practice rooms before. It doesn't have to be anything special, but finding a space where you feel comfortable and allowed to raise your voice (And probably your gain) is crucial to this process. P.S. I also need your info. I don't want to get through the casting process and realize you're unavailable when I need you or any of those other complicated details.
