they're all of characters. the first one is of my two characters, Taryn (girl) and Lan (horse). Lan is also the guy in the third pic, he can change into a horse at will. that's the only animal though, just horse and human, whenever he wants. they are from a story i'm attempting to write, though i haven't gotten far at all.
the middle picture is another character from a different story. her name is Celeste. her story takes place in the same world as Taryn and Lan's, just many centuries later. it's a magic world, that's kind of stuck in the 1500's, but everyone has magic, there's democracy, and a few technological advances, like basic indoor plumbing and a few other things. no cars or electricity though.
