>>8033839>>8034069nta, but just as an idea, Picasso painted this at 16. He was perfectly able to paint in a more classical or "realistic" style, as his early paintings, but even his blue, brown and early 20s period shows. Picasso is famous for his cubist paintings, but it's far from his only production, he has in fact, varied a lot during his life.
It's perfectly reasonable to say that you don't like Picasso or anything, but to call him "objectively bad at painting" is just nonsense.
