Medvedev, these aren't technical flaws. Besides, everyone has their own relative standards of beauty. Technical standards are: depth of field, focus "in the right place," smooth tonal transitions, sharpness (microcontrast in the image). As long as you think in cliches and stereotypes, you'll never achieve anything more than banality. Furthermore, if you've noticed from the history of photography, the technical aspects of a photograph very often diverge from its artistic value. Henri-Cartier-Bresson spoke (wrote) about this, and naturally, he wasn't alone. I hope this name means something to you, and you can also Google it online.
Beauty and aesthetics in portrait photography are still important.
Medvedev, It's not so critical here that it's worth making a big deal about.
