The eyes are the most important part of the human face, and also the most difficult to draw. The step by step process guides through an order with is common for many artists, but always remember to worry about the shades rather than the order to shade in.
The first step is always a light outline. A 2H pencil was used to outline the eye, and the iris, with some indication as to where the eyebrows are.
When shading in eyes, it helps to do the darkest areas first. The pupil is your first priority. Shade that in darkly, with a 2-4B, but remember to leave a space for the catch light. Next, line the top eye line, and the darker area around the iris.This will take us to our next step, which is shading the iris. Make sure that you are blending in the dark parts at the edge of the iris with that in the interior, you don't want it to look like an outline. Also, remember the catch light and which parts are darker and which are light, refer to the eyes section if you don't remember.
Next, shade in the corners of each eye, and add the eyelashes. Remember to use quick strokes with a sharp pencil when doing eyelashes, because you want them to look natural and come to a point at the tip.
Your last step is to indicate the line where the eyelid folds in and shade the eyebrows.
