Instructions: Having just said that the face has shape even without the eyeball, that doesn't mean we can skip it altogether, does it now?
Let's sketch it in. Don't use white, use a mix of pale grey-beige and then brush over with the skin tone - I've found that this combination very closely resembles the actual colour of an eyeball (the skin tone is generally reflected on the highly glossy surface). Do not add highlights to this eyeball yet. It's a waste to work in the glossiness at this point - it'll be painted over by the iris and pupil anyway.
What's more important, though, is that the eyeball's shape is consistent with the shading you've done on the eyelids. If you've been thinking right, it should fit right in. If you've messed up, the eyeball will look like a golf ball pushed into an ill fitting hole. Keep imagining the round shape of it, and if it helps, sketch the outlines of the round shape on a separate layer and then shadow the eye below it accordingly.
Common Mistakes: Pure white for the eyeball.
Instructions: The iris is completely round. For the most part, some of it will be hidden by the eyelid - if you hide only a little, the eye will look widened, shocked and staring (such as in the example I'm painting here), while hiding half or more will give the eye another expression altogether: perhaps indolent, seductive, sly.
Like the eyeball, never cease to imagine the iris as a round thing. To make absolutely sure, always paint the full round thing on a separate layer and then simply erase the bit that would be hidden by the eyelid. Like previously mentioned, we see the eyes, and we definitely see if something's messed up. A non-round iris will make it look alien and crooked - a neat thing if that's what you intended, but not so neat if you are aiming for a natural look.
So, pick a dark, random colour (nothing too extreme) and paint in the iris. Then on top of that, paint a lighter colour that will leave a slightly darker edge. Not all eyes have this darker edge at the outskirts of the iris, but we're settling for it this time around.
imilarly, the pupil is COMPLETELY round, no doubt about it. Paint in a round, dark circle in the middle of the iris. Just for the feeling's sake, dab a blotch of white on top of the iris and pupil, just to see how it would feel. There's the eye, suddenly a little glossy.
Common Mistakes: As previously mentioned, there is a tendency to make the iris less than round.
Instructions: There are no dark sketch-lines in a face, so it's time to get rid of them. There are two easy ways to do this - either you simply delete the layer, or you do as I did here: paint over them. I've found that painting over something rather than simply deleting it occasionally helps the liveliness of a picture. So for the sake of this exercise, paint over, don't delete.
What we have after we've done that is an eye that likely looks slightly messed up. We've used the lines as crutches, forgetting to shade the folds instead of letting simple lines do the talking. So the next mission is to do the highlighting and shading in the areas that are now looking stupid. For this, I use a brush that is either just a hard edged round one, or something similar to this:
