Identify the type of character your drawing is going for. In this one, I was striving for a more calm character, even though it could vary. After you have identified it, how will the head shape be? If you're going for a more gentle person, the eyes will probably have a downward tilt to them at the ends, the chin will slope gently, and everything will look refined. For a more wily character, you may make them have wild; carefree hair with a rougish charisma (you can't help but love them). Try to strive for one word that can describe that person, and make your appearance based on that. (Sorry for the mouthful, this step is almost finished) For this character, the eyes have an upward tilt to them and if drawn right, it'll look like she is nearly bouncing with held in energy. Sidenote: For the image I DID NOT use my own image, I used an example of who I'd count as a Gentle character. (Mitsuki from Full Moon wo Sagashite)
