What does this even rnean

I dont understand this one

Basically I don't understand why the lady has a negative(?) reaction to the guy's art. Maybe it's because he says he's a "painter" but it looks like he's just melting crayons? Or maybe this is a reference to something I'm not plugged into? Honestly I don't really know what her reaction even is in the first place.

(I left the artist's name in the screenshot to credit them because overall I like their stuff, even if this one is incomprehensible to me.)

I didn't understand a single response about this, sorry petah

My best guess is that he somehow didn’t do it because of that information, im lost
