Kids Reward Sticker Design Prompts: Cookie Giving Thumbs-Up

Create a series of vector-based sticker designs featuring a cookie character giving a thumbs-up. These illustrations should be crisp, high-contrast line art suitable for die-cut sticker formats, with no shading or gradients and a transparent white background. Focus on playful, happy expressions and bold outlines that appeal to children and work well as reward stickers for kids’ activities and achievements.
