Kawaii Cactus Sticker

Create a cute kawaii sticker-style illustration on a transparent background: a smiling green cactus character in an orange terracotta flower pot, centered and filling most of the square canvas. The cactus has one large oval main body with vertical ribbed segments, two raised curved arms, glossy lime-to-deep-green shading, thick dark-green outline, and a soft white sticker border around the entire silhouette. Add exactly 3 cactus sections: 1 central oval body, 1 left upward-curving arm, and 1 right upward-curving arm. Add exactly 24 visible thorn clusters, each a small orange base with pale cream star-like spines, distributed across the central cactus and both arms. The face should be adorable and cheerful: two large glossy black oval eyes with white highlights, two pink circular blush cheeks, a wide open smiling mouth with dark interior and pink tongue. Place one large red-pink flower on the upper left of the cactus head with exactly 6 rounded petals and a cluster of small yellow dots in the center. The pot should be warm orange terracotta with a thick rounded rim, darker orange shading, glossy highlights, subtle speckles, and visible brown pebbles/soil at the top; include exactly 7 visible stones along the pot opening. Use vibrant digital cartoon rendering, soft gradients, high contrast, polished sticker art, no text, no watermark, no extra objects. Background should appear transparent, optionally shown with a light gray checkerboard preview pattern to demonstrate transparency.
