I don't know how close you want to stay for the vanilla design, so I don't know if any of these suggestions are useful, but who knows^^ Personally, I don't like the vanilla one so I wouldn't mind something quite different.
I would remove the gloves and maybe add some jewelry like armbands instead. But then again, the gloves don't actually look bad, I just don't really like them stylistically^^ Maybe you could also add some more detail to them, especially to the opening (whatever that part is called). Right now they look a little bland.
Also, I assume you tried to give her thigh high boots? And while I quite like those, I fear they're not going to work without model changes, so I suggest having them end at the knees instead and also add some more detail to those.
And then there are the metal panties... At least that's what I assume this material to be. I'd just change the rear part of those completely so that it no longer looks like metal.
Hopefully some of that can help you and if not, at least I tried
