Why does he look nothing like Elians

Elians: That's simple! The sex between each of Alice's ocs determine the skin tone!

Elliot: Because I am male my skin tone is lighter then Elians. It shouldn't have been by a lot.

Me: But I couldn't find the tone I wanted. So most people wouldn't think that he's Elians twin. But I did make sure they had the same hair and eye color. :3
