i understand that you want the parametric roof structure to be outdoors surrounded by trees and park with people sitting and standing under it the structure should have a concrete floor and be made of wood the render should be set in an evening setting with the sky filled with birds the area should also have a lot of grass and pathways around it to create this image i would start by placing the parametric roof structure in a natural outdoor setting surrounded by trees and park i would add benches under the structure for people to sit and relax the concrete floor would be placed under the structure to provide a stable base to create an evening setting i would adjust the lighting to give a warm soft glow to the scene the sky would be filled with birds adding a sense of movement and life to the image the grass and pathways around the structure would be added to create a sense of depth and natural beauty finally i would add people to the scene sitting and standing under the structure enjoying the peaceful atmosphere and the surrounding nature the combination of the wooden structure concrete floor evening setting and the presence of people would create a harmonious and inviting outdoor space architecture
