When I first started writing novels, I made my characters ideal--nice body, perfect hair and eyes that glowed. Because I could. Because it was fun to create what wasn't real. A fantasy.
But I quickly realized that perfect characters could be a big yawn.
What makes a character interesting is the opposite of ideal. Etienne St. Clair in ANNA AND THE FRENCH KISS is really short and Bianca in DUFF struggles with her weight.
That's what I like to read about because it's REAL. Real is the new COOL! :D
Besides, what makes a character truly appealing isn't that they look like a god to everyone else--that's very subjective anyway. It's that they appeal to that other character you're writing about in the book. *wink* The way the freckles dance on his nose when he's smiling. Or how her blond eyelashes look translucent in the sun. That's what makes readers turn the page!
