Create a striking illustration for a men's phone case featuring an Australian man and his dog, capturing the rugged, adventurous spirit of Australia. 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 that convey confidence and warmth. His hair is short and messy, with natural brown highlights. His expression is one of calm strength, with a slight smile or smirk, and he stands tall and relaxed, hand resting on the back of his dog, an Australian Kelpie. The man wears a practical outfit for outdoor activities: an olive-green, short-sleeve shirt with rolled-up sleeves and weathered khaki cargo shorts with small rips or dirt marks. His sturdy boots and a brown leather belt with a multi-tool and flashlight highlight his preparedness for adventure. The Kelpie, sleek and agile with a glossy black and tan coat, stands alertly by the man's side, emphasizing their bond. The background is minimalistic with a pure white color, subtly hinting at the Australian outback with a blurred silhouette of red earth or distant mountains. Natural, warm lighting enhances the earthy tones of the man's clothing and the dog's coat, creating soft shadows that highlight their features. This design conveys a sense of adventure, strength, and companionship, appealing to those who love the outdoors and the Australian way of life.
