Create an upper body character portrait of a young woman, featuring long, straight sunburst yellow hair against an almond green background. She wears a dark banana yellow shirt, simple jeans, and has dark emerald green eyes. Emphasize a highly detailed and beautiful digital art style, suitable for trending on Artstation, in 8k resolution. Add subtle touches like golden earrings and a silver simple necklace. She appears confident and matured, embodying a 20-year-old with a natural form. Avoid overly exaggerated features or anatomy errors, maintaining realistic proportions. The scene is free from monochrome or excessive surreal elements. Ensure clarity and elegance without distortions or extraneous features, capturing a serene, aesthetically pleasing character illustration.
