Distant trees were deliberately painted closer to the top of the artist's canvas than were the nearby flowers. The artist was clearly taking advantage of the distance cue known as relative height to convey the scene properly.
Explanation:
Here a work of an artist is depicted in such a way that the distant trees were painted closer to the top. This kind of technique used by artists is termed as relative height. This relative height used in visual and art is a concept used while drawing distant objects.
While drawing a landscape the distant objects like trees or mountains seem to very smaller and higher than the objects seen near. Hence the artist use this effect of portraying the distant object as being higher or smaller in their own perspective.
