Flux 1.1 Pro Ultra 9 / 10
Judge's noteThis is another top-tier result, particularly strong in spectacle, composition, and surface rendering. Its battle mechanics are slightly less readable than those of the two leading entries.

Seedream 3.0 7 / 10
Judge's noteFifth overall: highly imaginative and energetic, but less controlled than the strongest four images. Its excellent spectacle does not fully overcome muddier small-scale forms and confusing overlaps around the brightest effects.
Architecture & Interiors Isometric architectural illustration of an ancient Chinese temple complex showing multiple pavilions, gardens, and ceremonial spaces. Include proper roof structures and traditional ornamentation.

Flux 1.1 Pro Ultra 8 / 10
Judge's noteRanked 6th of 13, this is a strong and comprehensive response with especially clear isometric presentation. Architectural crowding and uneven structural plausibility keep it below the more refined compounds.

Seedream 3.0 5 / 10
Judge's noteRanks 11th of 13. The appealing miniature aesthetic does not overcome the loss of architectural precision caused by soft focus, simplified ornament, and incomplete framing.
Complex Scenes An astronaut and a deep-sea diver playing chess together inside a submarine.

Judge's noteFifth overall, with especially strong clarity and material rendering. Slightly ambiguous chess interaction and a spacecraft-like cabin character keep it below the more coherent leaders.

Seedream 3.0 5 / 10
Judge's noteRanked 11th of 13, this is visually ambitious but misses an important part of the requested setting. Environmental ambiguity and malformed miniature objects outweigh its strong framing and color.
Ghibli style A girl and a giant fluffy creature napping in a wildflower meadow. Reproduce the art style of 'My Neighbor Totoro' by Studio Ghibli, with Miyazaki's soft character designs.

Flux 1.1 Pro Ultra 9 / 10
Judge's noteRanks second, with one of the strongest emotional relationships and exceptionally appealing surface treatment. Slight ambiguity around the girl's lower body and a more decorative interpretation of the requested style place it just below the leader.

Seedream 3.0 6 / 10
Judge's noteRanked ninth, this is visually competent but misses an essential part of the requested action. The awake creature is a significant prompt failure, so the strong meadow rendering cannot lift the overall assessment into the higher tier.

Flux 1.1 Pro Ultra 9 / 10
Judge's noteRanks 1st of 13 for its unusually direct and polished fulfillment of the brief. It offers the strongest combination of prompt fidelity, clean execution, and practical logo readability.

Seedream 3.0 4 / 10
Judge's noteRanked 11th of 13, this remains recognizable as a coffee-brand logo but misses several explicit requirements. The wrong background and multiple leaves are more consequential than its adequate readability.
Hands & Anatomy A realistic photo of a hand holding a red apple, with all fingers clearly visible.

Flux 1.1 Pro Ultra 3 / 10
Judge's noteRanks last because the apparent six-digit hand directly defeats the task's anatomical objective. Attractive fruit rendering and clean lighting cannot compensate for this critical failure.

Seedream 3.0 6 / 10
Judge's noteRanks 9th of 13, with a more complete digit display than several lower-ranked images. Its softness and simplified hand anatomy prevent it from joining the stronger photorealistic results.
Photorealistic People & Portraits A bride on her wedding day, smiling with tears of joy in her eyes.

Flux 1.1 Pro Ultra 5 / 10
Judge's noteRanks twelfth because it is technically attractive but misses the defining tearful emotion particularly clearly. Its strongly posed glamour treatment further separates it from the requested natural emotional moment.

Seedream 3.0 8 / 10
Judge's noteRanks third because its emotional expression is among the clearest in the set. Slightly processed surface texture keeps it below the most photographically convincing results.
Surreal & Creative Prompts A library where the books are glowing and floating in mid-air, illustrated in a magical realism style with dramatic lighting and rich atmospheric colors.

Flux 1.1 Pro Ultra 3 / 10
Judge's noteRanked last for this specific prompt despite its excellent craftsmanship. Replacing glowing, floating books with hanging lanterns is a critical subject mismatch, so technical strength cannot rescue the requested result.

Seedream 3.0 6 / 10
Judge's noteRanked 7th of 13, this image has attractive cinematic lighting but noticeably less controlled book construction than the higher-ranked entries. Because the airborne volumes are the primary subject, their geometry and lost page definition weigh heavily in the overall assessment.
Text in Images A storefront sign that says "Open 24/7" in neon lights, nighttime urban photography.

Flux 1.1 Pro Ultra 9 / 10
Judge's noteRank 3 of 13: This is among the strongest results for the central readability test and realistic neon construction. Its comparatively enclosed composition gives it slightly less artistic reach than the two higher-ranked images.

Seedream 3.0 6 / 10
Judge's noteRank 10 of 13: accurate primary text keeps this solidly relevant to the brief. Coarse rendering, limited façade detail, and weaker secondary signage prevent a higher placement.

Flux 1.1 Pro Ultra 5 / 10
Judge's noteRanked 9th of 13, this succeeds as a dramatic Earth illustration more than as an aerial photograph. Its conspicuously artificial surface textures are the principal limitation.

Seedream 3.0 3 / 10
Judge's noteRanks 13th of 13 because its impossible geology defeats the central realism requirement. Recognizable atmospheric and lighting cues cannot compensate for that fundamental failure.
