In this work, Costa utilizes the transparency of watercolour to build a world where mountains and valleys are redefined by intersecting lines. The medium allows for a soft bleeding of color that mimics the atmospheric haze of a long journey, while the underlying geometry provides a sense of direction and order to the rugged terrain. It is a study of how we perceive the horizon—not just as a distant line, but as a series of shapes that guide the eye upward.

The vertical composition emphasizes the scale of the environment, inviting a feeling of quiet exploration. By stripping the landscape down to its essential silhouettes, Costa captures the spirit of travel and the internal compass that leads us into the wild. The interplay between the structured shapes and the watery pigments suggests a harmony between the human desire for orientation and the untamed beauty of the natural world.
