When creating an artwork, the human brain needs to use which side predominantly in order to focus on the artmaking process?

The discovery in a difference in the way of thinking of
the two halves of our brain can be attributed to research by a psychobiologist named
Roger W Sperry. His work revealed that the right half of the brain is responsible for
processes that involve intuition and the ability to process information in a
simultaneous way. Artists first have to be able to create a complete picture of the art
form in their brains and then break it down to make decisions on the color, material,
etc. to be used. This would require an extensive use of the right
half.

The left half of brain on the other hand is the part
that can handle operations which need to be done following a sequential order with the
final product emerging as the pieces are put
together.

Though, the way the two halves think is not
exclusive, the importance of the right half can be judged from the fact that the
percentage of artists who are left-handed is substantially higher compared to the
percentage of left-handers in the general public where it is one in ten. This follows
from the fact that the movement in the right half of our body is predominantly
controlled by the left half of the brain and vice versa.
