I like how they used the tip of the pencil to recreate the shape of a mountain. This provides a new perspective. Using the pencil to recreate a scene that relates to the Swiss brand (i. the Swiss Alps).
What I like about this poster is that it has a good use of white space. And lots of food. The characters don't need to be overlapping what draws the eye, and let you continue reading it after pulling you in. Very simple graphic design.
