modify the existing visualization to reflect a full autumn season while preserving the original daytime lighting and clear blue sky keep the same composition weather conditions and natural sunlight with consistent shadows transform all deciduous trees so their leaves are in rich autumn colors mainly yellow orange and golden tones conifer trees such as pines and spruces must remain green grass should stay mostly green with a slight autumn tint without turning brown add a natural layer of fallen yellow and orange leaves scattered on sidewalks and ground surfaces to enhance realism the scene should feel warm vibrant and fully autumnal but still bright and sunny with no change in weather or lighting conditions
