SCENE DESCRIPTION:
A confident, well-groomed bald man in his 30s-40s stands in a pristine, modern bathroom. He has just completed his morning shaving routine - his freshly shaved head gleams with a healthy, clean shine. Soft morning sunlight streams through a large window, creating warm, natural lighting with gentle shadows.

PRODUCT ARRANGEMENT:
{products_text}

All five products are prominently displayed on a clean white marble bathroom countertop, arranged in an appealing, organized manner that showcases each product clearly.

- Warm morning light streaming through windows
- Color palette featuring dark green (#1d4d41) and gold (#c5993e) accents in towels, fixtures, or background elements
