Atmospheric Palette Knife Coastal Tempest on Coarse Linen

Full prompt

A wide desktop seascape executed on coarse unprimed linen with bold palette knife work, portraying a stormy ocean pounding against dark coastal headlands. The painting features low-key tones of slate grey, stormy blue, and deep petroleum green. Sharp angular sweeps of the metal knife create crisp ridges of foaming sea spray crashing over submerged volcanic rocks in the midground. The foreground displays frothy backwash receding in scumbled, semi-transparent strokes of bone white and silver. Low stormy clouds hang heavy in the sky, rendered with broad horizontal swathes of charcoal and muted lilac, establishing a brooding, moody desktop ambiance with exquisite textural depth.
