Topographic Map Contour Study

A topographic contour map line drawing on plain white paper, concentric irregular contour lines showing land elevation, a peak at the centre with closely spaced inner contours, contours spacing wider as the slope descends, a river line crossing the lower-left quadrant, a benchmark symbol at the summit, thin even brown ink for contours, a single blue line for the river, no shading, no color fill, no gradients, no hatching, generous white margin, cartographic survey style, no text, no letters, no numbers Art direction controls: deep cobalt, warm cream, and charcoal, a centered hero composition with deliberate negative space, quiet and editorial. --ar 3:2 --stylize 80
