Using REFERENCE_0 as the kitten identity, create a clean WeChat-style sticker-pack preview sheet on a plain white background. Transform the real photo into a soft, semi-realistic cute 3D/cartoon gray kitten with plush fur, round proportions, and gentle expressive body language, while preserving the kitten’s overall gray color, small ears, baby face, and soft fragile look.

Layout: Arrange exactly 6 separate sticker poses in a 3-by-2 grid with generous white spacing and no borders.

Sticker poses, exactly 6:
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, cheerful greeting pose.

Add a solid medium-gray square placeholder over the face area of poses 1, 3, 5, and 6 only, as if censoring or reserving space for future text/expressions. Do not add any text. Keep the sheet polished, adorable, consistent in character design, and suitable for a finished sticker/emoticon set preview. Use {argument name="sticker count" default="6"} stickers, with {argument name="background color" default="plain white"}, in a {argument name="art style" default="soft semi-realistic cute 3D cartoon"} style, based on {argument name="character" default="the gray kitten from the reference photo"}.
