z-image portrait generation: realistic vs. artistic style comparison

Using the same subject, this compares two prompt directions to showcase z-image's photorealistic texture and artistic expressiveness in portrait generation. The realistic side emphasizes natural skin texture, soft window light, and shallow depth of field to verify the model's fidelity to materials, lighting, and lens language; the artistic side adds painterly color blocks and highly saturated light to test its stylized composition and color control. Prompts are submitted directly via the schema's prompt field, with a 16:9 aspect ratio to achieve a more cinematic horizontal composition. It serves as a reference sample for portrait prompt writing and helps developers compare the differences between realistic and stylized outputs when integrating z-image, assessing how prompts affect imaging results.
