The cloud rock boasts an organic hand-trowelled plaster texture with random, irregular shallow ridges and recessed creases spread across the whole surface. The uneven, soft undulating striations flow freely without fixed directional rules, featuring uneven thickness of trowel marks and subtle uneven layered relief. Natural irregular cracks and winding faint indentations interweave with the broad sweeping hand-smoothed streaks, delivering an unrefined artisanal tactile surface with soft, blurred edge contours on every embossed mark.
