Do you mind if I download this and play with it?
I really like it by the way, but I don't think it's what I would classify as a silhouette. No big deal, of course. I agree that the flowers could have been lower. Back to having a reflector (which I know you didn't), I wish you had a more classical lighting pattern on her face. I think you could have bounced some in, as it is it's almost like you had a kicker and a fill light without a main, if that makes sense.
