Prompt
A pictorial surface made from individually placed beads acting like rounded tesserae, with small gaps and no flat fills, in the manner of a Celtic enamel bead hoard. The Cailleach, the Celtic divine hag of winter, a tall old woman in a dark hooded shawl with a long staff striding across a snowy highland moor at dawn: a weathered stern face under the hood, a flowing grey cloak billowing in the wind, her staff striking the ground to freeze a small loch into white ice, a pale sun on the horizon and bare dark mountains, in a wide frame.
Light: a pale cold dawn rim on the hood and cloak in silver and pearl beads, the snow in white and pale blue beads, the ice spreading from her staff in a bright cyan, the mountains in slate and deep violet, a thin gold bead sun; palette of silver, pearl, white, cyan, slate and violet with a thin gold; stark, cold, glittering.
Wide 16:9 frame. A dignified, respectful depiction in an authentic Celtic spirit; no readable ogham, runes, inscriptions, letters or logos anywhere, only plain interlace and knotwork borders.
