Ancient castle in fog with luminous fantasy flora

An ancient, moss-covered stone castle, half-hidden in a dense, ethereal fog. Delicate, luminous fantasy flora creeps up its walls, and a small, iridescent frog sits on a gargoyle, observing the mist. The scene is rendered with a soft, painterly aesthetic, evoking the romanticism of J.M.W. Turner, with a focus on atmospheric light and subtle textures.
