After glazing, you should add again more hair on the whole surface of the koala. Such steps help to draw fur with maximum realism and volume.
Probably, you noticed the fact that the eyes of the koala were covered all the time. At our school we always paint this way, specifically for the reason to reach a critical view of the characteristic form. When you paint the eyes in an earlier step, the animal becomes alive right in that moment, giving the feeling that it looks already fine even it is not still perfect. Therefore, we are brushing the eyes in the last moment in a stage when - even without eyes - the form looks convincingly.
With permission of Sam Nassour, this koala was painted by our student, but in airbrushing technique. This image was chosen on purpose, because it contains big amounts of different fur textures.
