Okay, so you're doing it. Just wanted to try and answer your question re. delicate features, which, as Bonsoir said, are best suited to a pixie cut.
Have a look at Mia Farrow. As B said, classic gamine type - small, bird-like bones, pretty, chiselled features with nothing in the face that jars. Everything is on a small, delicate scale (apart, perhaps, from the eyes, which have an almond-like slant to them).
People like Grace Kelly and Jean Sebourg are of a similar ilk.
I could never have a pixie cut, as, while I have quite delicately shaped eyes and mouth, my nose and jawline could never be described as such (not with out thousands of poundsworth of painful surgery!), so the style would jar on me and never look right.
Good luck with yours though!
