I would not call the lady busted but she is no Lanfear. She is a beautiful woman even but Lanfear in both forms that she appears in the books is supposed to be arrestingly beautiful; the most beautiful woman anyone has ever seen.
Personally when I think Lanfear I think Eva Green but that's way above their budget.
And speaking of the Forsaken, can you imagine them trying to recreate any scene with Graendal?
