Ink art, watercolour sketch: Extreme low-angle, scruffy ink-stained terrier yearning upward. Hopeful cerulean blue eyes, focal point, gaze into parchment-textured void, subtle watercolour washes. Arthur Rackham's intricate ink, Egon Schiele's expressive contours; delicate cross-hatching, bleeding washes. Monochromatic sepia, charcoal. Subtle chiaroscuro on rough fibrous paper. Poignant longing; faint ink splatters, abstract watercolour wisps hint at unseen sky.
