Create a portrait of a young child with a joyful expression, wearing a mix of bright, clashing colors and playful patterns. Artistic style should be a mix of whimsical and surreal, using digital painting as the medium. Use a medium telephoto lens with an aperture of f/2.8 to create a shallow depth of field, focusing on the child's face and outfit. Lighting should be natural, with soft, diffused light to enhance the cheerful atmosphere. The background features a playful mix of abstract shapes and vibrant colors that complement the child's outfit. Focus points include the child's expressive face and the intricate details of their clothing. Apply color grading to enhance the vibrancy of the colors, and use a vignette effect to draw attention to the subject. Add a touch of motion blur to the background shapes to create a sense of playful chaos.
