Content-aware fill might have been a bit quicker than cloning but the quickest and easiest way for me is to just paint onto additional layers to change the f$@# to an abstract meaningless tag.
This took about 60secs.
You don't need AI to make her look less tired. The facial features adjustments in PSE (and I suppose Ps) are quick and easy to use.
You're the one going around claiming you are a professional photographer and based on my experience over the years these basic edits are a skill a competent professional photographer has.
If you are too lazy or have no interest or time to learn some basic skills in manipulating images that's fine but I certainly then don't have time to waste doing them for you, at least not for free 😁
I've shown it can be done without AI; the rest is up to you.
While you're at it, a useful homework excercize would be to remove the "rabbit ears" coming out of her head in the background.
First, I'm no pro so take anything I say with a pinch (or three) of salt! 😁
I can see the mum's point of view. I assume these are to sell the clothing? So flatter the model and flatter the clothes.
I'm not really sure that urban/gritty with it's connotation of gangs really fits with "family" or the target market? Outdoor/sports possibly? Also I don't find the poses that flattering to the model or the clothes, the squat does nothing for the thighs/hips/abs of the model and hides most of the clothes. From the other shots you've posted she looks far better, (and younger), when you shoot from her eye level or above, not below the chin.
With the edits, forget AI or algorithmic auto tools. There's a simple way of creating a couple of layers that you can then paint, or paint a mask, with a soft and light opaque brush by hand with a pen tablet. You can easily soften features and enhance structure quite subtly by this method, (it lightens or shades usually using a brush at around 6% opacity). Forgotten exactly how to set it up, but I picked it up off a web tutorial and it seemed a common and established process.
