Hoja de Stickers de Gatito Gris

Using [the gray kitten from the reference photo] as the character identity, create a clean WeChat-style sticker pack preview sheet on a [plain white] background. Transform the reference pet into a [soft semi-realistic cute 3D cartoon] gray kitten with plush fur, round proportions, and gentle expressive body language, preserving its overall gray color, small ears, baby face, and delicate appearance. Layout: Arrange exactly [6] separate sticker poses in a 3-by-2 grid with generous white spacing and no borders. Sticker poses: 1. Sitting upright facing forward, paws together, tail curled beside the body. 2. Crouching low and peeking forward with wide eyes, playful and timid. 3. Sitting upright with one paw raised high, showing pink-and-dark paw pads. 4. Curled up sleeping peacefully, eyes closed, tail wrapped around body. 5. Jumping upward with both paws forward, small motion lines and a faint oval shadow underneath. 6. Standing on hind legs with both paws raised outward, showing paw pads, in a cheerful greeting pose. Constraints: Place a solid medium-gray square placeholder directly over the face area of poses 1, 3, 5, and 6 only, as a placeholder for expressions or text. Do not include any text. Maintain strict character consistency across all poses.
