A cute 3D rendered cartoon boy, wearing an olive green jacket, khaki shorts, and a beige baseball cap. He has large, expressive eyes, a friendly expression, and carries a brown backpack. He's wearing off-white sneakers. The style is reminiscent of 3D cartoon character design, with smooth, polished textures and no visible brushstrokes. The background is a simple beige color, focusing all attention on the character. The lighting is soft and even, creating a warm and pleasant atmosphere. The overall style is cheerful and friendly, suitable for children's products or game character design. The image is rendered in a style similar to contemporary 3D animation character design. Think of the clean lines and smooth surfaces of Pixar-style animation, but with a slightly more realistic rendering of the materials.

A high-quality, front-facing photograph featuring a professional dog trainer (female or male), aged 30-40, smiling with a friendly expression. They are wearing clean, professional work attire, such as a custom polo shirt or vest, possibly with a brand logo (if provided). Their posture is confident and warm, with one hand gently stroking a well-behaved Golden Retriever or Labrador Retriever in a seated position (representing the positive results of the training). The other hand is either naturally at their side or pointing forward in an inviting gesture. The image may subtly incorporate elements of professional dog training tools, such as a treat pouch worn on the waist or a professional training leash held in the hand. The background is pure white, and the overall atmosphere is professional and trustworthy, conveying a love for animals and professional service capabilities.
