So sorry, I forgot to add my experience and setup. I sadly just use my phone, though I'm looking into getting a mic. As for experience, I have been cast in multiple fandubs with an old server called Undead Dubs, and also am currently working in the project Your Turn To Abridge: Fandub By Majority.
For Reko, I have my same note about your Sara audition about your extra noise, but I also have a quick note about your tone. I really like the natural warmth in your voice and I don't think you have to push it like you did in that first take. You're getting amazing expression here and really good variation. But that first couple of lines feel like you're pushing your voice down. You have a lot more room to play when you're not straining.
