Jacey looks a mix between these two models once she cuts her hair, with her facial features more akin to the girl on the left, though her hair color is more coppery. She has a dusting of freckles and a certain grittiness about her that comes from being pushed around at the Conservatory.
Kit's appearance is a little between Alex Pettyfer in this photo and the model in the right photo. He has a bit of a rumpled appearance sometimes, and is always pushing the rules slightly to accommodate his humor. He has light green eyes.
I imagine Sayler as sort of a Clemence Poesy, with longer, thicker, and lighter blond hair, and more prominent cheek bones. She is also very tall, with a cool outward demeanor and grey eyes.
Tristan is like a younger, more bubbly and less pretty version of Katy Melua.
Voila. I don't know who he is, but he's a younger version of Halfman. Age him up a little and give him salt and pepper hair.
Looks somewhat like the tribute from District 4.
So these are just some character pictures for various characters (some haven't been introduced yet) that I have found. I hope to be posting more of Flyboy on figment soon!
