>>45890428It's less about the art being Western and more that self-taught artists tend to lack discipline and a willingness to reform their methods. You can see mistakes like lack of measuring the head and features, bullshit perspective and drawing in symbols rather than understanding structures (like Rosa's oversized slug-like tongue).
Once they can make something that's presentable, they don't wanna hear anything bad about how they draw and you're just a "hater" if you insist otherwise. There are Jap artists who are just as bad or worst, sure but they don't tend to have the popularity or the money which is a bit excusable. At least with artists that are in demand, the expectations are a bit higher.
