I like Sakura's nose. Vegeta has an evil, pointy nose. Look at Sakura, she has the messy, yet stylish sort of hair. Stick to the spiky look for guys and the wavy, elegant hair for girls. You can even modify Sailormoon's hair.
Younger girls have pony or pigtails.
Just remember to practice the eyes and the hair. The knights of Magic Knight rayearth have the shiniest hair. Ranma people have puffy thick hair. The best hair style does not have to be long.
