Create an image featuring a family of four posing together in an elegant setting. Change the following features: 1. Alter the attire to be casual yet stylish, such as colorful shirts and jeans. 2. Replace the background with a park or outdoor scene, with trees and grass instead of curtains. 3. Include a playful dog beside the family instead of a child actively posing. 4. Adjust the lighting to be bright and sunny for a cheerful atmosphere. Ensure there are no brand references in the image.
