Answer:
Line
Step-by-step explanation:
If John is having difficulty following a path visually in his art piece, the element that he should consider adding to help solve this problem is Line.
Lines in art can be used to guide the viewer's eye and create a visual path. By incorporating various types of lines—such as curved, diagonal, or leading lines—John can create a path that leads the viewer's eye through the artwork, directing attention and providing a visual flow. Lines can help establish direction, movement, and flow within the composition, aiding in creating a clear path for the viewer to follow.
