Drawing eyes in profile and three quarter view is different from drawing them head on. At these angles, certain things like the waterlines, and the setting of the eye in the socket will be emphasized. The eyes may even appear to be different shapes.
In summary, start with a sideways "V", pay attention to how the waterline curves and follow it, keeping in mind that it may be more visible at certain angles. In quarter view, the setting of the eye in the socket is more visible, and the eye is usually more curved on top and flatter on the bottom.
