Bill Brownridge, Under a Winter Sun presents a luminous northern winter scene built from thick, rhythmic strokes of colour. A broad frozen river fills the foreground, its surface shimmering with lavender, turquoise, and pale coral as light scatters across snow and ice. At the centre, two small bundled figures skate across the frozen expanse together, introducing quiet human warmth and scale against the vast landscape.

A dark screen of evergreen trees rises beyond them, painted in deep indigos and midnight blues, with rounded blue mountains receding into the distance. Above, a soft, glowing winter sun hangs in a sky layered with pinks, mauves, and pale gold, bathing the entire scene in cool, radiant light. The painting balances stillness and motion, capturing both the hush of winter and the lively sparkle of reflected light.
