Craft a sophisticated coloring page tailored for teens, spotlighting the portrait of a rockstar girl. The visual style should be simple line art, comprising meticulously drawn fine lines that define the girl's features and fashion. The backdrop should contrast deeply with the detailed black and white lines, lending an air of drama to the page. The rockstar girl's demeanor should exude confidence, with her attire reflecting a rocker aesthetic complete with a leather jacket, statement accessories, and a rebellious charm. Enhance the composition with subtle musical motifs like sound waves and musical symbols. The page's crisp linework provides teens with ample room to experiment with shading techniques and develop their coloring skills. Maintain a full-page format to provide a satisfying coloring experience. --v 5.2
