Can anyone guess who I am drawing

Hint: it is a female VOCALOID

Bailey is for sure a big fanenby (Acid called them Fanboy, due to Bailey being assigned male at birth), but embarrassed about the poster, which was gifted to them by Acid (Canon actually!)

If you want entire thing (the poster), just tell me in comments

Maybe I'll add something into background (it is on canvas btw)

Any idea for background?

Yoo guys! Today is my #spawnday!

Today is my Birthday!!! :3

Yaaaaayyy

When you can't use drawing program, so you use notes app instead (I literally used Google keeps)

While finishing it, I would be interested about one thing

Shipping between my OCs (which OC do you ship with other of my OC)?

I'll rate them 1-10

caption this?

It was Otomachi Una

I kinda ruined it with the outline imo
