Celeste, the b/w study is helpful. I think another thing is percentages or ratios of shapes. Most really awesome works will have asymetric value percentages. (In other words, if you classify, or group, values into middle, light, and dark values these will not be 33-33-33. More likely you'll see say; 61-16-23% or-50-21-29% or even 70-25-5% distribution. This is pleasing to the eye.
