I've known quite a few artists over the years, and most are egotistical af. I even make fun of artists in my own comic (to the surprise of my readers.) Being humble and noticing your own weaknesses forces you to improve.

If the artist who drew this keeps this arrogance, I guarantee his art will look the same in another 10 years, no matter how much time they claim to devote to it. Mediocre/plain/visually lazy at best. Why improve when he's so enlightened and perfect as is? He won't.

You also can't write for shit if every character in your comic is a strawman for you to beat down, instead of understanding other points of view.
Grow up, dude.
