An Expressive Brush

I enjoy painting sunflowers.  Looking closely In the center of the flower before the seeds begin to form to me it is like looking at a carpet closeup, but that is just me.  When I paint the center then I need to think carpet so that my brush moves loosely in that thought.  I know that sounds like I am out in left field, but I have noticed I have been doing that more lately.  There seems to be a difference between painting something in a structured way compared to letting your thought of the place or thing being transferred to your brush when applying the paint.  I have found fine tuning, if any, is much more creative when applying the finishing touches.  Lately in painting, I believe if we think less and express more we will have an expressive brush.
