First, the bad news:
"A comic for africans" <-- "Africans" should be capitalized.
The two black men talking has a typo in its title:
It should be "African" instead.
The title: "A comic for Ethiopians" Why this choice?
If sarcasm is what you want, why pick on a particular country, why not be more general with the title?
Next, the good news:
Enjoyed your dialogue, background, and characters in
the 1st one.
Ditto my remarks on the 2nd one.
Enjoyed the background and the characters in the 3rd one. As far as the dialogue, these characters are quirky! How could these brothers' parents have woken
them up in the first place if they weren't alive ALREADY? This dialogue makes them non-boring.
Enjoyed the characters and the background in the 4th one.
Liked the two choices of men in the 5th one.
