MONA LISA IS THE CENTER WHICH MAKES HER THE FOCAL POINT BECAUSE SHE'S THE FIRST THING YOU SEE

THE LADY IS ISOLATED FROM THE HOUSES IN THIS PAINTING

IN THIS PAINTING THE FACE TAKES MY EYES RIGHT TO THE PERSON WHICH MAKES THE FOCAL POINT

THE BACKGROUND COLORS MAKE THE RED WHITE AND BLUE STAND OUT AND MAKES IT THE FOCAL POINT

EVERYTHING IS EMPHASIZED, THE SHADOWS, CLOUDS AND PEOPLE SO IT MAKES NOTHING EMPHASIZED.

THE CONTRAST OF THE SHOES MAKES THE SHOES THE FOCAL POINT.
