Create a professional character reference sheet for an original Sci-Fi Courier named 'NOVA'. The character must have short cropped silver hair, glowing violet eyes, and be wearing a weathered tan flight jacket with neon blue trim and a heavy utility backpack. Organize the sheet in a clean grid on a plain white background. Include a three-view turnaround (Front, Side, and Back) alongside a row of four facial expression studies: Neutral, Determined, Exhausted, and Grinning. Render in a 2D Digital Illustration style with dramatic rim lighting and sharp textures. Constraints: Use readable labels for each view; maintain strict character consistency across all views; no background clutter; aspect ratio 16:9.
