Set Decoration in Ayu's MVs

[Embleu]

I really like the set decoration in "Alterna" (the "Hopes to Be a Star" scene) and "Marionette". Now that I'm in a film-making class and one of my upcoming assignments is to make a music video, I'd perhaps like to replicate those looks. Does anyone know the kind of styles/decor used in each of those videos? For example, is the decor in "Marionette" Victorian or what?

P.S.: And if, as a bonus, you could offer tips on how to achieve those looks on a budget (I live in the US BTW), I would be really, really greatful.* Hehehe.

*Sic. That was a pun.
