Hey yeah thats harsh man. Real people are going to look like real people. Even models look like real people before it all polished up in the processing.
I think it's up to you to adjust and shoot and process in flattering ways for each individual.
So her skin isn't perfect.. most people's isn't. there are ways you can handle it.
You have the colour of her dress and the graffiti, the the city in the distance to play with. Maybe less grey sky, more of that foreground vibrance.
Her expression works and seems genuine. Her body language feels a bit awkward and defensive. Probably nerves from posing, even if you don't particularly get on with her, you are in control and trying a more playful dialogue between the two of you could have been helpful to get her relaxing.
Yeah this too, i've definitely had shoots with people who didn't want to be there and were prickly with me. You can try to be playful and help them loosen up, sometimes works, sometimes not. You can only really try to be in control of the situation and try to find something that works.
