Writing Exercise - describe someone's face

In this exercise I was asked to pick someone that I do not know very well, for fear that my prior impressions of someone I am familiar with may interfere with the writing.
Well, it is completely not an easy job for me. One of the purposes of the exercise is to write with coherence and continuity. On top of that, I need to work on more details. I do admit I am being too general and kind of evasive about the details when writing. I am hoping to hone my writing skills with these exercises step by step.

Rachel's Face

Rachel has a face that tells stories. Her oval shaped face would not keep people at a distance, and her thick shoulder-length hair, with loose wavy ends, probably suggests her easygoing and carefree temperament. Her forehead is partially covered by bangs, which makes her bushy black eyebrows less obvious. She has sparkling eyes that smile, even without heavy makeup. These eyes are slightly upturned at the end, with a deep crease. She has a thin but clear nose bridge and a fleshy nose tip. It is believed by traditional Chinese that such a nose indicates wealth. However, I would rather interpret this wealth as an inner one, because it is easy to tell from her smile. Rachel is not at all hesitant to show her teeth confidently with a wide, warm-hearted smile. Her lips are thin, teeth white and straight. Her chin is of medium length and tapers smoothly. Above all these features, Rachel maintained a healthy tanned complexion unlike ordinary Taiwanese girls, for she is sporty and travels a lot, especially into the wild or natural reserves. Needless to say, she really has a lot to tell about.
