FLUX 3 Image 7 / 10
Judge's noteThis is a clear, charming adventure illustration with effective environmental leading lines. It falls short of the top tier through relatively generic surface design and less refined character interaction.

Seedream 5.5 10 / 10
Judge's noteThe strongest image overall, combining professional-level composition, cohesive 2D styling, and evocative storytelling. Its carefully controlled details and sense of discovery make it exceptional within this set.
Architecture & Interiors An ancient Roman bathhouse interior with accurate architectural details - marble columns, mosaic floors, arched ceilings, and steam rising from pools. Natural light from oculus openings.

FLUX 3 Image 5 / 10
Judge's noteThe rendering is strong, but the exposed underfloor construction is a substantial mismatch for a historically coherent operating bathhouse. This task-specific architectural flaw outweighs much of the image's polish.

Seedream 5.5 9 / 10
Judge's noteThis is the strongest image in the set, combining architectural credibility with excellent material rendering and spatial organization. Its minor ornamental simplifications prevent a flawless score.
Complex Scenes A school classroom of children and a teacher, each student engaged in a different activity.

Judge's noteThis is the strongest overall balance of prompt fidelity, believable interaction, and ensemble composition. It provides genuine individual activity diversity while maintaining unusually consistent spatial and anatomical coherence.

Seedream 5.5 6 / 10
Judge's noteStrong photographic realism distinguishes this image from several more artificial-looking alternatives. Its substantial failure to provide different activities nevertheless prevents that realism from translating into a high overall score.
Ghibli style A forest spirit standing among tall trees. Replicate the artistic style of 'Princess Mononoke' by Studio Ghibli, with Miyazaki's detailed environments and mystical creature design.

FLUX 3 Image 6 / 10
Judge's noteThis ranks sixth because its accomplished illustration technique is offset by a substantial mismatch in the requested character style. The environmental painting is strong, but the central figure reads more as a high-fantasy humanoid than a closely matched film-style forest spirit.

Seedream 5.5 8 / 10
Judge's noteThis ranks fourth as a polished, coherent interpretation with an attractive atmosphere and well-integrated creature. Its more contemporary fantasy styling makes it less specifically faithful than the leading images.

FLUX 3 Image 9 / 10
Judge's noteRanked 3rd of 12, this is among the clearest and most faithful responses. Its slightly conventional composition and lighter SALE contrast are minor limitations rather than substantive defects.

Seedream 5.5 6 / 10
Judge's noteRanked 8th of 12, this succeeds more as a decorative lifestyle still life than as a focused sale graphic. Its attractive rendering does not fully offset the weaker message hierarchy and inconsistent typographic integration.
Hands & Anatomy A yoga practitioner in a complex pose, arms and legs fully extended (full-body view).

FLUX 3 Image 9 / 10
Judge's noteRanked 1st of 12, this is the strongest combination of prompt accuracy, demanding pose, and coherent anatomy. Minor surface softness and a conventional studio treatment keep it below a flawless 10.

Seedream 5.5 3 / 10
Judge's noteRanked 11th of 12, this contains a critical extra-limb failure despite its attractive photographic treatment. The anatomical impossibility must outweigh the quality of the setting and lighting.
Photorealistic People & Portraits A black and white close-up portrait of a freckled woman with an intense gaze.

FLUX 3 Image 6 / 10
Judge's noteThis ranks ninth, with strong literal prompt adherence but noticeably less convincing rendering. Its intensity cannot fully compensate for the rigid expression and artificial-looking skin and hair treatment.

Seedream 5.5 10 / 10
Judge's noteThis ranks first for its combination of photographic credibility, precise execution, and complete prompt fulfillment. No conspicuous generation artifacts are visible at the supplied resolution, and the result reads as a finished professional portrait.
Surreal & Creative Prompts A snail whose shell contains a miniature city skyline, depicted in a hyperrealistic macro photography style with intricate architectural details and ambient lighting.

FLUX 3 Image 8 / 10
Judge's noteRanked fourth, this is among the strongest images for clean macro realism and readable miniature construction. Its restrained atmosphere and slightly patterned anatomy place it just below the more compelling leading compositions.

Seedream 5.5 5 / 10
Judge's noteRanked twelfth, this is the least successful integration of the shell and miniature city. Competent natural textures prevent it from being a failed image, but the split-shell construction and simplistic architecture significantly weaken the result.

FLUX 3 Image 9 / 10
Judge's noteThis is the strongest overall balance of prompt accuracy, readable typography, believable wrinkles, and focused presentation. Minor stiffness in several creases keeps it short of a flawless result.

Seedream 5.5 4 / 10
Judge's noteGood typography and fabric detail are outweighed by the conspicuous human/mannequin mismatch. The image is less usable as coherent product photography than several technically weaker but internally consistent alternatives.

FLUX 3 Image 5 / 10
Judge's noteRanked tenth because prominent illegible technical labels constitute a critical failure for this particular brief. Attractive photography cannot compensate for the conspicuous generated-text artifacts.

Seedream 5.5 8 / 10
Judge's noteRanked fourth because its photographic atmosphere and readable text are exceptional within the set. Mathematical inconsistencies and a less notation-heavy board keep it below the more faithful leading entries.
