A WhatsApp sticker, square, with a thick white die-cut sticker border and a soft drop shadow, one finished birthday graphic. Inside the die-cut shape is a vivid saturated party backdrop: a gradient from hot-pink at the bottom-left into tangerine at the top-right, with warm bokeh dots, bright sparkle glints and a few white light streaks. A dense burst of multicolour confetti (turquoise, yellow, violet, lime) flies across the whole sticker. Generous glossy balloon clusters in turquoise, yellow, violet and red, with tied ribbons, fill the top-left and bottom-right corners and frame the text without covering it. Headline, exact text "HAPPY BDAY", in two stacked lines: "HAPPY" on the upper line and "BDAY" below it, larger and heavier. The lettering is bold modern brush script laid down with a loaded round brush. Strokes are thick and confident with lively thick-to-thin modulation and a slightly rough dry-brush drag where strokes lift. The letters connect in a fast, free flow on a bouncing baseline, and sizes vary slightly for a hand-made rhythm. Each letter is a different punchy colour (yellow, turquoise, lime, violet, white-hot pink) with a thick crisp white outline and a soft dark-magenta drop shadow, so the letters pop hard off the saturated background. Add small glossy highlights on the brush strokes and a few tiny star sparkles on the letter tips. The headline fills about 80% of the sticker width and sits slightly tilted upward, about 5 degrees, for energy. Small supporting line, exact text "from The Crew", in a rounded white hand-lettered style with a soft magenta shadow, centred under the headline at about 30% of the width. The mood is punchy, cheerful and high-energy, readable at thumbnail size. No other text.
