Euphoric Ghost
"She has been around here all of her life so she truly is athletic." What does being around here make her athletic? Maybe write a little more on what this athletic image looks like? How does her arms and legs look like, does she have belly or is it so tight that you could see muscles there?
"She never likes sitting still for very long. If you see her outside she's always doing something that involves a lot of exercise. She's always running and enjoying life. She's rarely sick, and always healthy." That's not really physical appearance?
Honey, the person who reviewed above me, is overly a**l about obvious details and this you really shouldn't take to heart. Summer's profile is better than many that I've seen, and it's consistent. It flows and stays to the character. All you really need to do is maybe add a bit of background to define why she's so perky and maybe an in depth personality analysis to made her seem more three-D than she already is, mmkay? <3
