This is...so weird...! Don't be offended, cause I mean it in a good way. First off, the title is so contradicting to what's actually shown on the picture that it made my mind race: what the hell is the author talking about?! So I started thinking that, for instance, the "normal" human race got eradicated somehow in some super-cool futuristic battle and these humanoid creatures are the new humans now! (Maybe even more-so because of the human skulls at their feet!)
Also, they have weapons and more or less, primitive clothing, so now I'm thinking that this super-cool futuristic battle is still going on and this couple is just a pair of badass humanoid slaying motherfuckers!
Maybe I'm reading too into the context, but I really love this picture! It's telling a story to me, even if the story isn't true lol! And of course it's drawn and colored amazingly! Good job!
(Or did you mean human couple as in the two skulls?! WHAT?!)
