Cyanotype Bat Silhouette Art Prompt

A vertical 9:20 cyanotype artwork of a single bat hanging upside down from a thin branch. The entire image should feel chemically printed rather than digitally illustrated. Use only deep Prussian blue and the pale blue-white of exposed paper. The bat is almost entirely a silhouette, but delicate variations in blue reveal the folds of its wings and the texture of the branch. Place the branch diagonally across the upper third of the composition, leaving most of the lower frame empty. A few tiny pressed leaves appear as pale ghost-like shapes. Let some areas become darker where the photographic emulsion would naturally have accumulated. The result should resemble an old experimental photographic print made in a darkroom. Slight chemical unevenness, imperfect exposure, soft edges, and tiny stains are welcome. No conventional illustration outlines, no bright colors, no glowing fantasy effects.
