zen-inspired moonlit composition，moderate-sized jade moon positioned along the rule of thirds, radiating soft halo through rice paper-textured sky ，foreground: sparse ink-black reeds in xieyi (freehand) brushstrokes, curved stems echoing moon's arc ，mirror-like lake surface dissolving boundaries between reality and reflection, fractured lunar reflection rippling in monochrome indigo ，minimalist negative space occupying 70% frame, celestial balance achieved through asymmetric emptiness， color restraint: midnight cobalt gradients, moonlit mercury whites, single accent of celadon in water ripples ， style fusion: song dynasty ink wash austerity + modern light physics, reeds rendered with dry brush texture against liquid-smooth lake ，no mountains no stars no florals
