Peter Cheung’s As the Light Changes is an expressive equestrian landscape showing a group of horses grazing and standing in a bright green pasture beneath a dramatic blue sky. The scene is loosely painted, with the animals arranged across the middle of the composition and a small barn or shed set back in the distance.

The painting’s strength is its contrast between light and shadow. The pasture glows with intense yellow-greens, suggesting sunlight breaking across the field, while the sky and background are built from deep blues, purples and dark greens. This creates the feeling of shifting weather or late-day light, as though the scene is caught at a passing moment when sun and shadow are moving quickly over the land.

Cheung handles the horses with broad, energetic brushwork rather than tight detail. Their forms are suggested through warm browns, blacks, whites and blue-black shadows, giving them weight and movement while keeping the scene painterly and atmospheric. The foal near the centre adds tenderness and scale, while the grazing horse at right gives the composition a calm, grounded feeling.

As the Light Changes combines rural subject matter with a loose, contemporary approach. Rather than presenting a polished pastoral scene, Cheung emphasizes mood, colour and immediacy, capturing the changing light of the pasture and the quiet presence of the horses within it.
