Pet Apparel Replacement Mockup

Create a minimalist e-commerce mockup with a light gray background, using a simple two-image contrast layout. Place a small, rounded-corner reference image in the upper right corner, showing the back of a white, fluffy dog ​​standing on soft light blue fabric, wearing a beige knitted pet sweater with light blue trim. The sweater features a large cartoon dog face patch in brown, black, and white, along with the word "Smile" in red cursive, a small red cherry, a blue star, and a yellow crescent moon. Below the reference image, place a rounded light gray text bubble containing the following Japanese text in black sans-serif font: “像内のペットを猫に差し替え、元の像と同じ衣装を着せた状态にする。猫は面对または侧が見える向きで、完全がはっきり見えるようにする。” (Replace the pet in the image with a cat and dress it in the same clothing as in the original image. The cat should be facing forward or to the side, with its entire body clearly visible.) In the lower left corner, place a large, rounded image with a subtle dark border, showing a gray tabby white cat standing against the same soft light blue fabric background. The cat's body is slightly turned to the left, but it looks directly at the camera. Its ears are erect, and its large, round eyes are bright and alert. Its chest and limbs are white, while its back and tail have gray stripes. Its expression is calm yet alert. The cat wears a matching beige knitted pet sweater with light blue ribbed trim at the collar, cuffs, and hem, fitting its body perfectly. The sweater's pattern matches the reference image: red cursive "Smile," cherry blossoms, blue stars, a yellow crescent moon, and a large textured cartoon dog face patch on the side. The lighting is soft and even, giving the product photo a studio-quality feel, with realistic fabric texture, minimalist shadows, and an overall style that aligns with the professional aesthetics of a pet clothing catalog.
