Excerpt
One of the first things an artist becomes aware of when drawing an animal is that the animal body-- especially what we would regard as the "arms" and "legs"-- is configured quite differently from that of humans. The differences in the head shape may be a little subtler, which is why some beginners overlook them. In comparing the human head to an animal head, we notice that, otehr than the nose and the shape of the ears, everything else is built in pretty much the same way as it is with people. However, on closer inspection, we'll see that it is not so much the actual features of the head but where they are placed---and in what proportion-- that makes all the difference.
