A vibrant vector illustration of a young brother and sister, ages 6-10, playfully fighting over a tall glass of lemonade. The scene is set in a warm, cozy kitchen with bright colors, capturing their innocent expressions. The boy and girl reach toward the lemonade with determined looks; a few bright yellow lemons are scattered around them on the table. The style is clean, childlike, and colorful, with soft shadows and crisp lines, emphasizing the playful bond between them. The background should be simple but homey, to keep the focus on the children’s interaction.
