"Design a futuristic sci-fi helmet that combines elements from the 'Halo' game series and a flying vehicle. The helmet should feature a sleek gray and white color scheme with striking orange accents. Incorporate automotive visual elements such as streamlined curves, aerodynamic shapes, and metallic finishes, blending the robust, iconic design of a Halo helmet with the sleek, high-tech aesthetics of a flying machine. The overall design should convey advanced technology and a dynamic, vehicle-inspired look." --niji 6 --ar 2:1
