I dislike all of the faked images I see these days, where skin is retouched to the point that the people lose their "realness". I think it's a personal decision as to how much retouching is done, but I am just stating that my preference is toward little, to no, skin retouching on senior portraits. But then, I'm in my mnid-50's, and grew up in the era or real photography; but now, we are in the era of digital imaging, which is different from photography...the realism, the truthfulness, the veracity of a camera's pictures has become more plastic, less truthful, less realistic,less honest.
I think these look fine, real, honest, representational. The pictures show how he looked whenh he was graduating from high school in 2017; but as with so many things, there's a spectrum. We have people here who spend hours on images, and smooth skin and remove blemishes and create very beautiful images. There's no one, "right" answer.
The "norm" varies from person to person. Retouching used to be done with an airbrush on the actual negatives, and was expensive, uncommon, and rarely used; today, there ar epeople who have a 5- to maybe a 10-step process for every image they make...so....it's really up to you how you finish your photos.
