Mask Sleek Matte Black Surface Angular

Create a mask design featuring a sleek, matte black surface with angular contours. The eye openings should be teardrop-shaped, glowing softly in a serene blue. Incorporate subtle tribal patterns etched into the mask's surface, adding texture without overwhelming the design. The overall silhouette should convey a sense of strength and mystery, while ensuring it remains completely devoid of any brand references.
