Excellent render, well done.
From a technical standpoint though, it's all wrong. Polaroids were finicky at best, the flash would wash out the girl being that close, her pupils would be red, and a majority of the background would actually be in focus. The fixed lens was meant to take clear photos at all distances. Besides, the film was expensive as hell and even the vainest person wouldn't take a "selfie", she would have had someone else take the photo.
