In Geometric landscape XV, the traditional vista is reimagined as a series of intersecting planes and deliberate color blocks. Costa utilizes the opacity of acrylic painting alongside the soft bleeds of watercolor, creating a visual tension between rigid geometry and the unpredictable flow of pigment. The portrait orientation emphasizes the height of the land, drawing the eye upward through layered shapes that suggest mountains, valleys, and the quiet geometry found within the earth.

By stripping the landscape down to its essential forms, the artist highlights the inherent patterns of nature. The illustration style avoids unnecessary clutter, focusing instead on how light and shadow can be represented through flat segments of color. This approach invites a focused observation of the horizon, where the organic subject matter meets a disciplined, mathematical execution.
