My interpretation: The bird schoolboy is also an artist. Someone said that his art is bad, much to the latter's dismay. The eccentric and darkly-humorous Genevieve responded to this by stating that, no matter how it looks, art is art, even going as far as to threaten to stab the detractor's eyeball with the paintbrush. Genevieve is overall supportive, charismatic, loving, eccentric, honorable fictional artist.
Incredibly relatable one-shot comic, João! Beginning artists' art style can also be good. Rookie's efforts are also appreciated.
