Very neat! Do they have any names? I keep calling the first one "Aphrodite" in my head. She looks very Greek to me!
As for the unfinished one, I think she needs something more around her head. She has the gradient and symbol that are very busy on the bottom but her head is very plain by comparison. A smaller symbol on her cheek/forehead, or some sort of crown/diadem, or a blaze like you'd see on a real horse, or even an elaborate fancy hairdo would help, I think!
