Create a 3D chibi fondant cake art style image with high-quality rendering, smooth shadows, and soft gradients. The girl should be based on the reference image, preserving facial features, with long brown hair in two space buns, brown eyes, jeans, and a pastel floral cardigan. Add a thick white outline like a sticker and make the background transparent. She is sitting in lotus pose, hugging a Plumbob and pressing her cheek to it like a kitten.emoji
