Scale (with Relation to Proportion)

In this picture, Donald Duck is out of scale with the rest of the scene. Because the scale is not proportionate, Donald Duck appears to be too big, which can make him seem out of place.

In this picture, Mickey Mouse and Donald Duck have been made to scale with the train, which puts them in harmony with the scale of the train.

*these pictures show that you can find scale and proportion in just about anything, if not everything, in life
