 In Fig 3. notice how the nasal symmetry does not correspond to the flat occlusal plane of the teeth biting edges.

The front upper teeth all appear to be the same length due to the horizontal straightness of them. 

Fig 3

 Notice how the nasal symmetry corresponds parallel to the angles of the plane of the teeth biting edges.

These are important aspects and is reflected when ladies are re-styling eyebrows either raising or thinning them. Sometimes in an effort to increase the facial length appearance.

In Fig 4 What stands out to the viewer is the apparent pronouncement of the two central incisors. These are markedly larger in width and height and dominate the smile, whilst the side laterals and canines are discretely blended into the background of the triangular dark corridor at the sides of the molar teeth.

In comparison the molar teeth in Fig 3 which are boldly evident to any viewer fron the front and sides.
