Create a full-length photorealistic image capturing a wildlife scene: a lion integrated into the silhouette of a gazelle, keeping the lion's head, facial features, and skin intact. Design a background inspired by the natural habitats of both a lion and a gazelle, merging lush savannah landscapes with subtle hints of the gazelle's environment. Focus on harmonious blending of textures and colors, while maintaining realism and the distinctive characteristics of both animals.
