Create a striking, realistic illustration for a men's phone case featuring an adventurous Australian man and his loyal dog. The man is in his late 20s to early 30s, with a strong, athletic build and sun-kissed skin. His face is rugged with a strong jawline, light stubble, and piercing blue eyes that exude confidence and warmth. His short, wind-tousled hair has natural brown highlights. He wears an olive-green, short-sleeve shirt with rolled-up sleeves to expose muscular forearms and khaki cargo shorts showing signs of wear and tear. His sturdy, worn boots and a brown leather belt with a multi-tool and flashlight suggest preparedness for adventure. He stands tall and relaxed, one hand resting on the back of his dog, an Australian Kelpie with a glossy black and tan coat, bright eyes, and energetic stance. The background remains minimalistic, with a pure white color to focus on the man and the dog, complemented by a subtle hint of the Australian outback. Natural, warm lighting enhances their features using earthy tones like deep greens, browns, and sandy yellows. The illustration conveys adventure, strength, and companionship, appealing to men who love the outdoors and the rugged Australian spirit.
