I kind of think she's supposed to be an art witch. It's not exactly a broom she is holding, but a giant paintbrush. And the thing floating next to her is possibly a palette.

Looks like it, pretty cute! I don't think we need a specific tag for that though. Unless it's a "thing", I guess?

There's actually a lot of posts where you can use "palette" as a tag.

Good call, I'll add that and paintbrush.

I don't think the witch-related stuff needs to be removed though, since if you're looking for images of witches with brooms, you'll probably want to find this one, even if it's not a broom strictly speaking.
