Create a simple, elegant editorial illustration for a self-development ebook about social confidence and overcoming social hesitation. Show a young adult sitting quietly inside a subtle, transparent bubble representing their comfort zone. The bubble is beginning to open gently around them, with a small path extending forward toward two or three simple human silhouettes having a conversation in the distance. The person should look calm and thoughtful, not sad or distressed. The visual should communicate gradual progress, openness, and the idea of stepping outside one's comfort zone without changing one's personality. Style: minimalist line art mixed with a soft cartoon illustration style, similar to modern self-development books, psychology workbooks, wellness journals and contemporary personal-growth ebooks. Clean thin outlines, simple organic shapes, slightly rounded forms, subtle facial expressions, very few details, elegant composition, warm and reassuring atmosphere. Use a limited, soft color palette with muted pastel tones and plenty of white space. Keep the illustration airy, sophisticated and uncluttered. Avoid photorealism, 3D rendering, excessive shading, dramatic lighting, overly detailed backgrounds, motivational text, typography, or corporate stock-image aesthetics. Composition: vertical or slightly horizontal editorial illustration, centered subject, with enough empty space around the illustration so it can be placed at the bottom of an ebook page without Voir plus
