Valle otoñal tranquilo con roble y casita de piedra

A highly detailed, ultra-realistic photograph of a serene autumn landscape in a mountainous valley. On the left, a massive ancient oak tree with thick, gnarled dark bark and a full canopy of vibrant orange, golden-yellow and red autumn leaves stands prominently, its branches spreading wide. Soft sunlight filters through the foliage, casting warm dappled light and long shadows. In the foreground, a crystal-clear shallow stream flows gently over smooth rocks and pebbles, surrounded by lush green grass, colorful wildflowers in purple, pink, yellow and red, and scattered fallen autumn leaves. A winding cobblestone path covered with orange and brown fallen leaves leads from the bottom right toward a charming rustic stone cottage on the right side. The cottage has rough-hewn stone walls, a weathered tiled roof, a stone chimney with a thin wisp of smoke, small wooden-framed windows with warm interior light, and a wooden door. In the mid-ground and background, a tall waterfall cascades down steep rocky cliffs into the valley. Towering mountains and dramatic rock faces rise under a soft cloudy sky with golden sunlight breaking through, illuminating the autumn foliage on distant trees in shades of orange, red and yellow.
