What makes female face attractive?

Men are generally attracted to women who have fuller lips. The brains of Men see this as a sign that the woman is healthy and fertile.

Both men and women find symmetrical faces highly attractive. The more symmetrical a woman's face is, the right side is similar to the left side, the more attractive the woman is considered to be. 

Men are generally attracted to women with feminine facial features such as thin eyebrows.

Big eyes make a female's face more like a baby face. Big eyes make the person seem more receptive and kind. (See Why Do Men Find Women With Big Eyes Attractive?)

A small nose is considered a sign of femininity. The more feminine a woman's face looks, the more attractive it's considered to be. 

Cheekbones are more of a personal preference than a universal beauty standard for women. Some men prefer women with prominent cheekbones while others don't.

Facial proportions can make a person more or less attractive. If one feature is too big, then it might reduce the overall attractiveness of the face. (See What makes a woman physically attractive to a man?)

Men generally find women with soft hair more attractive than those with coarse hair. Generally, long hair makes the woman seem more attractive to men since it signifies health.

According to psychologists, the personal preferences a person develops can force him to get attracted to a certain type of face. Some men, for example, might only prefer women with sharp facial features, while others might only like women with round facial features.

Men in general prefer women who are not overweight. Any increase in weight that makes the face overly wide and the neck thicker is considered unattractive by most men.
