Well, eyes are said to be the windows to the soul. The old window is there because, no matter how modern our lives get, our souls, the essence of people, will never change, and they're as old as time itself. Also, each eye is in a window pane because even though each soul is unique and different from each other, we all make one race of people.

The eyes are odd colors because souls aren't the physical manifestation of the body. Rather, they're our spirit. And spirits, or the personalities of people, can have colors associated with them based on the virtues of the colors.

There are various things in those eyes that people might have in their souls. In the purple eye up in the upper left pane is a unicorn for fantasy (read: daydreamers). In the upper right pane is make-up for the people that are more concerned over their physical appearance (read: beauty is skin deep). in the lower left corner is poker, for people that love to gamble(read: waste of good money) in the lower left is an NES for gaming (read: non-Nintendo fans, you lose out because Nintendo was the original gaming system that everyone knew)

And I'd hate to forget the person that inspired this image. A wonderful friend of mine, ~DarksLilKitsune with her image Windows to Souls

The composition is mine. There will be some serious price to pay if you steal this. Not only from me, but from everyone I listed above as well.

(oh, check out this image as well for details on the eyes)
