Honestly I cannot comprehend this level of delusion and i cannot believe he isnt ragebaiting

I have no one to talk about this because none of my friends are chronicly online. I want to focus on one thing - his art. Like, that man thinks of himself as a new coming of Leonardo Da Vinci but he like- doesn't know any basics. He doesn't know anatomy, perspective, values, composition, shading. Like, anything. Atp my little sister draws better than him. And he still is 100% convinced that shitty stained glass painting that "took him years" (that he tried to sell for almost 2k even tho he copied it). I just cannot comprehend as an artist myself how you can be this level of delusional.

Fellow artists here please tell me yall see this and i'm not going crazy.
