Generate a full-length photorealistic image of an elephant, utilizing the frame and silhouette of a mouse while keeping the elephant's head intact, showcasing its distinct facial features. The skin should resemble the texture of an elephant, and fur elements should hint at a mouse's softness. The background should blend colors and textures inspired by both animals, incorporating savanna landscapes and urban environments to create a harmonious yet whimsical scene. Focus on lighting that highlights the unique characteristics of the combined creature, enhancing the surreal yet believable nature of the artwork.
