Create a full-length photorealistic image of an elephant showcasing the musculature and framework of a giraffe, while keeping its head intact, including distinct facial features. The skin should reflect the texture of an elephant, while the body has the elegant posture of a giraffe. Design the background to merge elements from both animals' natural habitats, featuring tall trees and grasslands, capturing the essence of African savannas. Ensure vibrant colors and realistic lighting enhance the scene, emphasizing the unique hybrid creature.
