Hm... Let's give this a shot shall we? I'll use an alternate personality version of my upcoming OCs
Name: Aria Skysong
Personality: Aria has never been the most talkative pony. She would like to make friends, but she feels like she doesn't have anything in common with anypony. Due to that feeling, she never has the courage to go out, meet new ponies, and make new friends.
Label: "The background pony"
Reasoning behind the label: She never stands out in a crowd, she always stays quiet and generally ends up not being noticed.
Looks: Since I suck at describing things, here's an image of her instead
Other: Um... Nothing else here I guess.
