I've tagged missing characters, except for the dog and the one with the cake. I don't know about the tiger in the background, but yeah.

The Pixiv title and description indicate these are all characters voices by Minami Omi (南央美), one of the artist's favorite voice actresses. This made it easy to ID the tiger from a list of her known roles. The one with the cake took a bit more work, and I'm still not sure about the dog.

I know that. I'm the one who added the Omi Minami tag and checked for her roles. Even then, I couldn't figure out the missing tags because I haven't seen them.
