Da Foto di Trekking a Schizzo con Pennarello

A loose hand-drawn marker and ink travel sketch based on the reference photo. Maintain the identical composition, featuring the [two hikers] with their poses, outfits, backpacks, and the mountain meadow setting. Simplify the scene into rough black ink linework and expressive, scribbled marker color fills against a clean white paper background. Preserve key landscape elements: the [large boulder on the left, grassy alpine slope, tree line, and distant snowy mountain peaks]. Style: quick outdoor field journal illustration, stylized postcard sketch, minimal and artistic.
