The front cover of the birthday greeting card should feature a vibrant and lifelike representation of a mountainous landscape, set against the backdrop of a clear, bright blue sky. In the foreground, a pair of well-worn, realistic hiking shoes are perched on a rocky ledge. These hiking shoes should be detailed, with scuffed leather, visible stitching, and untied laces lazily draping over the rocks.

Behind the shoes, a panoramic view of towering, snow-capped mountains stretches across the card, their rugged peaks piercing into the crisp sky. The mountains should be depicted in varying shades of grey and white to capture the play of shadows and sunlight on their surfaces.

Nestled in a cozy nook of the scene, a small, realistic campfire gently flickers, surrounded by a circle of smooth, round stones. Nearby, a metal camping mug rests on the ground, with steam rising from its open top, suggesting a warm beverage inside.

Above this picturesque scene, a single fluffy white cloud drifts lazily. Within this cloud, the name "Markus" is whimsically written in a soft, cursive font. The letters of "Markus" should appear as if they are part of the cloud's natural form, subtly blending yet remaining clear to the viewer.

Add a few green pine trees scattered along the mountainside, providing a splash of natural color. These trees should be depicted with detailed, needle-like branches that sway slightly in an imaginary breeze.

The overall color palette should emphasize natural tones: earthy browns and greens, the stark whites of the snow, and the deep blues of the sky. This realistic photographic style composition will convey the themes of adventure and the beauty of nature.
