Feedback for photorealistic image

Thank you everyone for the feedback! It's all invaluable. My summary of the feedback I have received:

The image needs to be clean because it's not useful to as many people looking old and noisy. For this reason, its lack of fidelity and crispness would result in a rejection. If someone wants it to look old, they can use a filter for it.

There are some anatomy issues that are pretty glaring. It's hard to see those sometimes when you've been staring at an image for awhile; I should take more breaks to get a fresh start and flip them canvas more to mix up my perception of the image.

The rendering errors, particularly the the one on the crotch, are quite bad and easily fixed. The solution to catching these will be the same as for the anatomy issues.

I can see the weird cut of the bikini being an undesirable element, but I think it's a more engaging image if it reflects the lower clothing technology of the fifties. I think that sort of thing should stay to differentiate it from images of modern swimwear. If this sort of thing gets rejected, though, I'd likely change course.

Again, thanks to everyone for the feedback!

A fun picture, but there are some anatomical challenges. The worst part is that it looks like her left leg is too far forward - and imo her pants look too big in the front for the squishy waist.

The image is quite noisy. 

You're girlfrien has very elastic hands: 

Emulating the vintage look does result in refusals, as the quality of a vintage picture is not up to our digital standards. And indeed, it is rather simple to get that look by using specific vintage filters. You should avoid that.

If it is good or not is for you to decide. What is wrong and will probably result in a refusal are the rendering errors. Her right thumb appears wrong. Her bathing suit pants have at least three seam errors. The crotch, the hip and under the naval.
