Illustrate a men's phone case featuring an Australian man and his dog, embodying the rugged, adventurous spirit of Australia with a focus on realism and detail. The man, in his late 20s to early 30s, has a strong, athletic build, sun-kissed skin, and a rugged face with a strong jawline, light stubble, and piercing blue eyes exuding confidence and warmth. His short, messy hair has natural brown highlights, and his expression conveys calm strength with a slight smile. He wears a practical outfit suitable for outdoor activities: an olive-green, short-sleeve shirt with rolled-up sleeves exposing his muscular forearms, weathered khaki cargo shorts with small rips, and sturdy, reliable boots. A brown leather belt holds a multi-tool and flashlight, signaling readiness for adventure. Standing tall and relaxed, one hand rests gently on the back of his Australian Kelpie dog, showcasing their deep bond. The Kelpie, sleek and agile with a glossy black and tan coat, has upright ears and bright, intelligent eyes filled with loyalty. Its athletic build and energetic stance complement the man's ruggedness. The background is minimalistic and primarily pure white, with subtle hints of the Australian outback like a blurred silhouette of red earth or distant mountains. Natural, warm lighting illuminates the duo, enhancing their features with earthy tones and creating soft shadows to emphasize the man's muscular build and the dog's sleek coat. This design conveys adventure, strength, and companionship, appealing to men who love the outdoors and the Australian way of life. It captures the loyalty and courage of the man and his dog, making it a perfect fit for a phone case with a unique, rugged Australian vibe.
