Our brain is divided into two halves, as most of us know: the left and right side. Each side processes information very differently than the other, and the biggest difference is the visual aspect.
The right side of the brain looks at visual reference as a whole, whether it be a landscape, object, or piece of artwork, and then works its way into noticing finer details.
The left side on the other hand, first sees the details and puts them together to form the bigger picture.
In simple brain is that the left side is the "Organization and logic" side and right side is the "Visual reference " side.
