Contrast-This is a good example of line because the lines of paint that bring your eyes down towards the girl holding onto the umbrella. The first thing I see in this picture are the paint drippings and then my eyes go down to the girl with the umbrella.
I have an obsession with eyes. I do believe that they are the windows to the soul. I draw eyes in a lot of my notebooks and on almost all of my school work. I find them so. I hope you like this awesome pic of a lot of this colorful eye :)
