I got a couple things to say here.
1) Surely if you are writing a book, You dont need an actual picture of your protangist, is that not the entire purpose of a book? to describe with words? Have you ever ever ever seen a book before that has specifically felt the need to put in a picture of the main character? i doubt it.
2) You coulnd't use these pictures anyway, You said they are not you, And, unless these chicks gave you personal permission to use their photos in a book, Its technically illegal
3) Without sounding like a cunt, Personally i don't think either is really 'Hot', Both look like they have put on FAR too much makeup, Both are sporting nasty ghetto duck face poses and i would honestly put both of them at a 6/10.
4) Good luck with your book.
