There are three things in particular that make this picture great. The bright red is reminiscent of Matisse. Thee contrast of the bright white really shines with the deep colors of the rainbow placed in the middle of it. And finally the rhythmic repetition of the circular shapes really help focus the eye and lead it around the picture. I think the composition is really great as well because the elongated male and female figures frame the center and help the eye stay where you want it. The picture is a great visual experience--well done!
