Green T. Rex Portrait Against a Mountain Sky

A close-up, profile view of a green Tyrannosaurus Rex, its reptilian scales detailed with texture, its large, intelligent eye gazing forward with a slight, knowing smirk. Sharp, serrated teeth are visible within its slightly open maw. The dinosaur's neck curves upwards, disappearing out of frame, against a backdrop of a vast, clear blue sky dotted with fluffy white clouds and distant, faint stars. In the background, majestic, layered mountains rise, their rugged peaks softened by atmospheric perspective. The lighting is bright and natural, suggesting daytime, with a subtle glow highlighting the dinosaur's features. The overall aesthetic is realistic with a touch of fantastical adventure, evoking a sense of awe and wonder. The image composition is a medium shot, focusing on the dinosaur's head and neck, with a shallow depth of field blurring the distant mountains slightly.
