Create an illustration for a men's phone case depicting an Australian man with his dog, embodying the rugged, adventurous spirit of Australia. The man, in his late 20s to early 30s, has a strong, athletic build with sun-kissed, weathered skin, a rugged face with a strong jawline, light stubble, and piercing blue eyes exuding confidence and warmth. His short, messy hair features natural brown highlights. He wears an olive-green short-sleeve shirt, rolled up to reveal muscular forearms, khaki cargo shorts with small rips and dirt marks, and sturdy hiking boots. A brown leather belt holds a multi-tool and flashlight. His pose is relaxed yet poised for action, with one hand gently resting on his Australian Kelpie, showcasing their deep bond. The Kelpie, sleek and agile, has a glossy black and tan coat, upright ears, and alert eyes. It stands at the man's side with its tail slightly raised, emphasizing agility and complementing the man's ruggedness. The background is minimalistic with pure white, subtly hinting at the Australian outback with faint silhouettes of red earth and distant mountains. Natural, warm lighting highlights the earthy tones of the man’s clothing and the dog’s fur, creating soft shadows. The image conveys adventure, strength, and companionship, appealing to those who cherish the outdoors and the loyalty of a canine companion, perfect for an attention-grabbing phone case with a unique Australian vibe.
