Oh my gosh thank you so much for drawing her, i absolutely love this and she looks so cute in your style! can i add this to her showcase page? (and maybe an utau art folder in the future when i stop being lazy)
All I can think of is Sophia Marie. Her creator started taking t at some point and is/was considering scrapping her in the future if i'm not mistaken, there's a video on it.
Requests are now open again! I am also willing to make utau designs/concept art for your singing children
You are also free to ask for more than one character
