This is a pretty cool idea, but as others have said, I think you need more elements that relate it to the 11th doctor.
The red corset is nice, but I think something lighter and either striped or plaid would be more recognizable. Suspenders also come to mind, and could be worked into a burlesque act, similarly a belt could also act as another "prop". Elbow patches on the jacket is an easily overlooked detail. Maybe pick up Tardis pin to replace your current, which looks to be an artist's palette pin, not sure how that relates to Doctor Who.
It's also rather obvious, and probably a choice made by the model to not change, but a more similar hairstyle is something else that would also help better relate the character.
