Arrange a single ridged acorn with several oak leaves in a close flat-lay study, showing the cap’s rough scales, the nut’s satin brown surface, leaf veins, and small stem details. Place the specimens on textured parchment with subtle overlapping shadows and a few natural imperfections. Use restrained botanical digital rendering, muted olive greens, umber, tan, and warm side light from the upper left. No text, no watermark.
