I apologize if I arrive late, but now that I started getting accustomed to Biro’s style I can safely say this isn’t definitely drawn by Biro.
Written, maybe, but not drawn.
In fact, I posted a similar question, which now I see is off-topic, about the art of the first episode of Airboy.
Admins/Moderators: please feel free to move my question in this section, and sorry for the mess…
