Prompt
Vertical 2:3 portrait framing showing a calm lake as the single primary subject, the water surface filling the lower half of the frame and mirroring the sky and tree line above it. A continuous band of mixed deciduous trees runs across the upper third, positioned on the left-third to right-third horizontal axis so the center remains a reflective seam between sky and water. Compose with a low-angle viewpoint slightly above water level to emphasize the mirrored surface and give the trees modest monumentality. Soft, diffused light sculpts subtle tonal separation with cool blue-green midtones in shadow and warmer, pale highlights in the sky. Textures are specific: glassy water with faint ripple lines, matte bark detail on trunks, and fine leaf edges catching soft rim light. Depth is moderate with the near shore occupying the bottom quarter in soft focus and the tree band resolving crisp in middle distance. Keep negative space vertically balanced so the sky occupies the top half and the reflection occupies the bottom half, preserving a centered horizontal horizon for a meditative symmetry.
