Tranquil Symmetrical Lakeside Treehouse Landscape

Full prompt

Tranquil landscape illustration composed with near-perfect mirror symmetry across crystal-clear water. At the center stands a flourishing green tree with a full rounded canopy beside a quaint cottage featuring white walls and a blue roof. Flanked on both sides by a dense dark-green forest, the scene exudes absolute calm. Scattered stones rest along the lower-left shoreline, while lush grassy banks line the lower right. Drifting gently on the water to the left of the center is a small wooden rowboat carrying two graceful white swans, casting crisp glassy reflections under realistic natural lighting, 9:16 aspect ratio.
