I like the use of colour and the abstractness of the picture. You can see it as many different things with your imagination, including a man with a beard. The only thing I would change is the contrast; some of the picture is quite hard to see, and that can be fixed by adjusting the picture's contrast in Photoshop or GIMP. The way you do it is by going into the Levels or Curves editor and designating the highlights, midtones and shadows. For highlights, click a pixel that is the closest to pure white, for midtones, click the pixel that is the closest to middle-gray, and for shadows, click the pixel that's closest to pure black. That way, the picture will be easier to see.
