No, I don't think the character is based on any specific mythological person. I do know her from some specific... Let me call it work of fiction. If I gave away what form it has exactly, that might be too big a hint. But there is something in the avi that might help with guessing what she is from!

Just so I understand it

you made an avi based on something where everyone can interpret it differently????

I mean colors/items, is that right???

for example like an book chara???

I think she might be from a song, cause there are notes flying around her, that aren´t easy to see.

Yes, you understand that correctly - somewhat like a book chara. But she's not from a book ;)

Toxic, the notes are indeed the hint I meant, but it's more than just a song.

Eh? I think I´m lost for now.

Had hopes it would be a Metal song.

More than just a song - a whole opera? XD Or ballet...?

Yes Mem, you're in the right track!

Oh my, I don't know nearly enough operas

I would say it is a rather well known one, but that might depend a bit on where you live.
Here it's a typical first one for taking a child to, but that's probably also because it is in my mother tongue. (hehe, hint for everyone who knows where I live, I guess ;))

Well, Ithink I'd be more familiar with a ballet, but the first that comes to mind is the nut cracker and then the swan lake, but that's not it XD

googled, and I'm just gonna guess as I go. Is it Norma?
