Design one single mobile app icon for the App Type, presented exactly like a real App Store or Google Play icon. Use the Icon Concept as one bold, centered symbol with comfortable padding, a strong silhouette, crisp edges and smart negative space so it reads instantly at small sizes. Render it in the Icon Style using the Color Palette with strong contrast between the symbol and the rounded-square background. Keep the design simple, original and iconographic rather than a detailed scene. Use an iOS-style squircle with smooth rounded corners, centered on a plain very light neutral background, filling about 70 percent of the square 1:1 canvas. Add a soft, subtle drop shadow beneath the icon. No device, hands, mockup, extra icons, text outside the icon, tiny details, hairlines, glow, sparkles, lens flares, watermarks or resemblance to existing app icons, logos or mascots.
Use these details:
App Type: "Sticker maker"
Icon Concept: "A sticker with one corner peeling back to reveal a simple smiling face"
Icon Style: "Flat illustration"
Color Palette: "Bubblegum pink with white and deep raspberry accents"

Your result will come out close to the example rather than identical to it. Change the details to make it yours.
