Question

The artist uses different types of lines in the painting. For example, he uses straight lines for the sides of the buildings and curved lines for the winding road and leaves on the trees. What is the vanishing point in the painting?

Answer 1

Can you show a picture of the painting, otherwise I cannot tell you an exact vanishing point for it.
A vanishing point is where all lines and planes in a picture meet and end.
For example, if you had this picture of train tracks, the vanishing point would be where you can no longer see the train tracks as they fade into the background of the mountains where I have marked.
It is also possible for a picture to have more than one vanishing point.
