Five difficult points to check with this prompt:
If this one image is generated, please zoom in and check the following points.

- Text Consistency (AI EVOLUTION 2026)
Is the text written on the cardboard sign rendered correctly without spelling mistakes, while maintaining a "handwritten" texture?

- Anatomical Accuracy and Interaction
Are the old man's "10 fingers" naturally holding the fragile object, a glass butterfly? Are the fingers dissolving into the background or is the number incorrect?

- Material Differentiation (Material Mix)
Are materials with completely different reflectivity and transparency—"old man's skin (wrinkles)," "chrome plating (mirror surface)," "glass (transparency)," "velvet (napped)," and "liquid (steam)"—depicted without contradiction under the same light source?

- Calculation of Space and Light (Ray Tracing Understanding)
Is the blue luminescence of the android reflecting correctly on the old man's glasses and surrounding metal? Are there no contradictions in the shadows caused by multiple light sources?

- Prompt Adherence and Attribute Separation
Is the specified arrangement of "old man on the left" and "android on the right" maintained? Is "Color Bleeding" occurring, where the color of the "red velvet" transfers to the android's skin or the old man's clothes turn blue?
