For being far from completetion, she's sounds really good. She doesn't slur at all either! And I read your YT description, if she's missing a bit of OTO, I guess that would explain the tiny bit of muffled-ness I think, but maybe it's just becuase her voice is so soft. What program did you record with?
Thank you ^^ I recorded in OREMO. And what exactly do you mean by muffledness? It's probably because her voice is soft, like you said, but it might be because of her oto if you mean that the lyrics aren't clear.
