Limestone Basin · Nested Sinkhole Forms

SUBJECT
One broad limestone basin at dawn, containing three nested sinkholes; a narrow footpath skirts their rims.

COMPOSITION
Wide elevated view; the largest sinkhole dominates the foreground, a smaller one sits midframe, and the smallest rests near the distant ridge. Keep the path as a thin scale cue and leave open sky above the horizon.

STYLE GUIDE
1. Shape & line
Build terrain from irregular nested contours, breaking each contour where rock has collapsed or eroded.

2. Color & light
Use stronger value separation in the foreground and compressed contrast in the distance; keep light direction consistent across every rim.

3. Texture & material
Place rock strata along exposed faces and finer weathering marks on upper surfaces; vary mark density with distance.

4. Composition
Use a large-near, medium-middle, small-far progression so the repeated landform establishes scale.

PRIORITY
Preserve the requested identity, count, action, composition and output settings. Apply the style rules within those constraints; a style reference must not replace the subject or layout. Within the style: Prioritize believable nested terrain, then depth through scale, then restrained geological texture.

AVOID
Avoid perfect concentric circles, uniformly detailed distance, fantasy glow, lettering, logos, and watermarks.

OUTPUT
One 16:9 landscape image with continuous natural terrain to the frame edges.

SELF-CHECK
Pass if three sinkholes read as separate depths and each rim has plausible broken geology.
