Aesthetics and balance are somewhat subjective. And then you have the word symmetry like, "Flex Wheeleer was the most symmetrical" bodybuilder. Nothing to do with symmentry, aesthetics yes, but even there you have some contrarians who complain about narrow shoulders etc.
And one of my biggest pet peeves is people (and they are many) who think this guy is a result of training, he could have trained his physique to be beautiful. Reality is that he trains like everyone else.
