It's good he's criticizing, but he comes off as a condescending major prick when he does it. Instead of coming off as helpful, he comes off as an asshat trying to make the other person feel wrong and bad for making something. He's done the same to me with my food truck, saying stuff like "sorry for getting mad over the people who want their lego people to drive realistic cars, i guess i'll just have to let them drive around in their Ford Volvo ToiletPlunger 294838-A all they want" "well some people just want to make it into a bucket of puke" "just because it's low poly doesn't mean you can get away with overdetailing. this is why i don't download vehicles 99% of them look like crap, like look at that wheel and tell me that's fit for blockland"
He's trying to say "this car seems too highly detailed / poly", but he says it in such a cunt-like way it becomes a whole different thing
