Create an illustrated logo depicting a Valkyrie with a serene and imposing expression. The face must convey confidence and elegance, with striking and sophisticated features. The helmet must have a detailed and stylized design, with elegant lines and subtle embellishments, like feathers, covering the eyes to give a mysterious and imposing air. Use a metallic color palette, como prata ou ouro, for the helmet and combine with a dark background or a deep, rich tone to create contrast. Incorporate subtle details and textures into the helmet to add depth and complexity, maintaining the simplicity necessary for the logo's versatility. Include the name "Valkyrie Cosmetics" with a sophisticated font that complements the face and helmet design, keeping the typography discreet and elegant.
