A charming pencil portrait of an extremely fluffy Highland cow peering over or through a rustic wooden fence, executed with delightful personality on pure white paper using graphite. Draw the Highland cow with an exceptionally thick, shaggy coat that appears almost cloud-like in its volume and softness, using varied pencil strokes to capture the flowing, windswept quality of the long hair. The coat should cascade in luxurious waves with the characteristic long fringe covering much of the face, creating that iconic "can barely see the eyes" look that makes Highland cattle so endearing. The cow's sweet face should show through the fur with large, gentle eyes rendered with photorealistic detail showing depth, moisture, and a kind expression that radiates friendliness. Include long, beautiful eyelashes, a broad soft muzzle, and perhaps the tongue slightly visible suggesting the cow might be licking its nose or showing curiosity. The facial expression should be incredibly sweet and approachable, perhaps slightly tilted head showing personality. Draw impressive curved horns with realistic texture and growth rings. The wooden fence should be weathered and rustic with detailed wood grain, knots, cracks, and aged patina, showing individual planks or rails with authentic farm fence construction. The cow could be leaning over the top rail, poking its head through rails, or resting its chin on the fence in an endearing pose. Add background elements suggesting a pastoral Scottish highland setting with soft-focus rolling hills, distant mountains in atmospheric perspective, wildflowers and thistles growing around fence posts, and perhaps stone walls or traditional farm buildings in the distance. Use careful shading to create the three-dimensional fluffiness of the coat while maintaining sharp detail in the eyes and face. This portrait should capture the irresistible charm and gentle nature of Highland cattle through expert observation and technical excellence.
