Gestalt is the visual phenomenon that our eyes see the whole object before we perceive the individual objects in the picture. Here at first glance, the skull looks like it has wings, but at a closer look, the wings are not made of feathers but out of weapons.

"HARMONY"

Unity or harmony is a group of objects that come together or belong together. The image above is a group of Spartans that makes the picture come together.

Individual images put together with a common theme is a collage. Each images has its own purpose but it starts to form its own unity.
