Design a captivating coloring page for teenagers featuring a portrait of a rockstar girl. The illustration should be presented in a simple line art style, characterized by crisp and fine sketch lines that emphasize the subject's features. This black and white coloring page should stand out with deep, rich contrasts, creating an impactful effect against the background. The rockstar girl's expression should exude confidence, and her attire should reflect a bold and edgy style, incorporating elements like a leather jacket, studded accessories, and stylish boots. Frame her with dynamic swirls of musical notes and a sleek electric guitar nearby. Ensure that the linework is meticulously detailed, inviting teens to explore shading and textures as they bring this rockstar character to life. To match the teen audience's preferences, maintain a full-page layout with clear lines for coloring boundaries --v 5.2
