Kawaii Cactus Transparent Sticker

Create a cute kawaii sticker-style illustration of a happy potted cactus as a transparent PNG. The main subject is one round barrel cactus with two raised curved arms, bright {argument name="cactus color" default="lime green"} skin, darker vertical grooves, glossy highlights, and a thick dark green outline plus a soft white sticker border. The cactus has a cheerful face with 2 large black oval eyes with white highlights, 2 pink circular blush cheeks, 2 simple curved eyebrow marks, and 1 open smiling mouth with a pink tongue. Add exactly 1 large red-pink flower on top of the cactus with 6 rounded petals and a cluster of small yellow stamens. Add many small star-shaped cream thorns with orange centers along the ribs and arms, evenly distributed. Place the cactus in exactly 1 terracotta flower pot, colored {argument name="pot color" default="warm orange terracotta"}, with a thick rim, subtle speckles, glossy white highlights, and visible brown pebbles/soil at the top. Use a polished digital cartoon rendering with saturated colors, smooth gradients, soft shadows, and a playful commercial sticker aesthetic. The background must be transparent; show no room, table, studio backdrop, scenery, text, watermark, or extra objects. Center the character, full body visible, portrait orientation, high resolution.
