The Twins Awesome
It reminds me of a bipolar disorder, when one of the twins aren't visible untill they show their actions.
Btw, great use of color to show the difference between good and bad. The spiral in the background makes it seem like they are in a constant struggle to control one another. Although, I think if the Sprial was just a tiny notches of shades darker, it would really bring the twins more into focus, instead of the picture as a whole.
