The closer you look into things...the more you'll see. I have found this particularly true in nature on bark and leaves. When you view them from a distance, you see one level of patterns and textures. The more you focus in, the more details within the patterns become visible. If you want to get crazy and bust out the microscope, then that's a whole different ball-game. I didn't quite feel the urge to work microscopically on this one, but I was thinking a lot about depth and layers.
