Man in robe making designs on dirt ground.
An artist preparing some sketches in the dirt.
Making designs doesn't imply the man is an artist. Designes on dirt ground aren't always sketches.
We have no idea if he is an artist, he could just be having fun. We have no idea what he is making in the dirt, so we don't know if he is doing sketches.
Just because a man is making designs in dirt does not mean he is an artist.
