Art Nouveau Panel of a Grey Heron Among Blue Irises in a Moonlit Pond

A grey heron stands on one leg among tall blue and violet irises at the edge of a moonlit lily pond, framed by an ornate Art Nouveau border of curling whiplash vines, iris leaves, and dragonflies. Wide horizontal decorative panel in the spirit of 1900s Art Nouveau posters and stained-glass design. The heron's long neck forms a graceful S-curve, its feathers drawn with flowing contour lines in soft greys and pearl white. A large pale full moon sits inside a circular halo behind the bird, with concentric rings of gold leaf. Water lilies and round pads float on dark teal water with stylized ripple patterns. Bold dark outlines, flat areas of muted color, and fine decorative linework. Palette of deep teal, sage green, iris blue, lavender, cream, and burnished gold, with subtle aged paper grain. Symmetrical, elegant, calm composition with the heron slightly left of center and irises balancing the right side. Landscape 16:9. No people, no text, no lettering, no signature, no logos.
