A high-fashion 3D editorial studio portrait of a stylish young woman sitting comfortably inside a giant, hollow 3D transparent neon lime-green glass letter "S". 

To keep the artwork completely unique:

1. She wears a vibrant lime-green oversized hoodie under a glossy black puffer vest, dark black tactical cargo pants with strap buckles, and matching lime-green chunky sneakers.

2. She poses confidently with one hand resting on her dark long hair, looking directly into the camera lens.

Dark charcoal-gray studio background with soft floor reflections from the illuminated glass letter sculpture. Sharp editorial studio lighting, sleek streetwear aesthetic, high-detail 3D render, 8k resolution. [Reference Image Rule: If I upload a photo (man or woman), preserve my exact facial features, gender, facial structure, skin tone, and hair from my uploaded photo while adapting this neon glass letter setup and streetwear outfit to fit my gender.
