You can de-emphasize this sort of thing very easily:
- dupe base layer
- desaturate and brighten it up a bunch, to taste
- add layer mask for full transparency (base layer shows through)
- "paint in" the background from the desaturated layer by airbrushing the mask as desired, blur the layer mask to blend any clumsy brushwork
- make masked layer translucent to taste
This takes like 5 minutes:
But I don't think the background is very distracting to start with..
It's really an unflattering look at "her". The dress looks like a tent, and it makes it look like she has absolutely zero bustline. The parking lot line intersecting with the bust, and the odd pooching out of the fabric at the neckline just all combine to make the clothing look awful. The easiest thing to do would be to clone out the trash can behind, and clone out the parking space white stripes, but no offense, this pose doesn't seem all that worth rescuing, to me at least.
My eye is brought straight to her arm and not her face, which I'm assuming you'd want to be the subject. I think it's also the way the background mingles with the underside of her arm which is what brings my eye there for some reason, as if it's highlighting it somehow. Still a nice portrait though
