You have a very nice composition here she is fairly well in focus your background is slightly blurred to keep from distracting. Overall its a nice family portrait.
Do I see delicate no not at all what I see is a very pretty girl in a somewhat shy pose but I have no reason to think delicate.
Your lighting is a little harsh as her nose is getting lost in the light.
Again you have a nice portrait you just didn't convey delicate all that well.
an attractrive woman, nice use of 3rd rule, but wouldn't it be nice if she were doing something "delicate" like smelling a flower, holding a baby, or a kitten, etc.
