This is very under rated IMHO. The pattern is unmistakable and the composition is what really sells me on this shot. This is such a textbook example of the rule of thirds. You might want to try using curves to add medium-strong contrast on this and perhaps a little more saturation to make it really pop. Still, I really can't understand why so many people voted below 5 unless there are just that many that don't understand what a pattern is.
Not sure if this is really a pattern, since these things grow where the seeds randomly fall. I suppose it is a pattern by some definitions, though. I do like it a lot. Composition and DOF work great here.
