This is one of my favorite ads thus far. I love that the photo has a vintage tint and the use of typography is brilliant. The blur in the middle of the type really conveys the idea of flying to good use
C that the artist created a mountain range out of different pictures of actual mountain ranges. The different colors make it easier to tell that each overlapping picture is a mountain and keep your eye flowing from one pyramid to the next nicely.
This image includes the detail of the trees in the foreground. It is spatially accurate as there is less detail in the mountains farthest away. These include the cross contour lines of the mountain to show definition and the variation.
