Jeune femme en robe grise face à un tableau de chimie

.Photorealistic digital painting of a young woman standing with her back to the viewer in a science classroom. She wears a form-fitting sleeveless light gray mini dress and black high-heeled sandals. Her long straight brown hair falls naturally. She stands with legs slightly apart and hips angled, arms relaxed by her sides, as if turning toward a chalkboard. In front of her is a large green chalkboard filled with white chalk chemistry formulas and diagrams (e.g., H2O, NaCl, Fe, Ba(NO3)2) with chalk dust and erased marks. The room features a dark purple wall and a wooden floor. Soft, cinematic lighting from above creates gentle shadows and highlights the texture of the dress and the figure. The mood is stylish, academic, and slightly dramatic, with a back three-quarter view.
