Prompt to image, in context

01 · Amazon cyber warriorgemini-3-pro-image-preview
Prompt

Concept art para um jogo de ação futurista: um guerreiro indígena high-tech com armadura orgânica e circuitos bioluminescentes, montado em um jaguar robótico blindado, patrulhando uma floresta Amazônica cibernética ao entardecer. As árvores são gigantescas, com implantes metálicos e folhas que emitem luz. Rios de dados digitais fluem como neon azul pelo chão. No céu, destroços de satélites formam constelações artificiais. Espíritos tribais aparecem como hologramas flutuantes integrados ao ambiente. Estilo: concept art para videogame AAA, com iluminação dramática, foco em atmosfera imersiva, mistura de natureza e tecnologia, alta resolução.

02 · Golden Gate HUDgemini-3-pro-image-preview
Prompt

Produce a 3:4 vertical bird's-eye infographic of the Golden Gate Bridge, combining the real photograph with layered white HUD engineering annotations. Insert a hand-drawn box in the lower-left corner naming the structure. Overlay complex technical notes: cable tension data, span dimensions, material quantities, truss and tower section diagrams, deck plan sketches, and major engineering characteristics. Style it as a HUD display with clean white linework and educational infographic clarity, while keeping the natural environment visible.

03 · Exploded product systemgemini-3-pro-image-preview
Prompt

Ultra-detailed exploded view of a product, metallic parts and electronic components floating in mid-air, perfectly aligned, revealing inner structure, futuristic technology aesthetic, 8K resolution, soft cinematic lighting, highly realistic.

04 · Commercial character figuregemini-3-pro-image-preview
Prompt

Create a 1/7 scale commercialized figure of the character in the illustration, in a realistic style and environment. Place the figure on a computer desk, using a circular transparent acrylic base without any text. On the computer screen, display the ZBrush modeling process of the figure. Next to the computer screen, place a BANDAI-style toy packaging box printed with the original artwork.

05 · Grim oil portraitgemini-3-pro-image-preview
Prompt

A close-up oil painting portrait, capturing a person in the distinct, grim aesthetic of Anton Sokolov. The style is characterized by heavy, expressive brushstrokes that define form and texture, and a high-contrast, dramatic chiaroscuro lighting scheme. The subject, who should have a stern or intensely serious expression (referencing the demeanor in the example images), is depicted with extreme texture and definition in their skin, emphasizing pores, wrinkles, and any distinguishing scars. If the subject has light hair, it is depicted as shock-white and highly textured; if dark hair, it is densely painted with distinct brushwork. The eyes are painted with depth and intensity, mirroring the profound and serious gaze seen in all referenced images. The lighting is hard and focused, creating deep shadows that are almost black on one side of the face, while a bright, sometimes colored, light catches the other side, creating a powerful, moody, and theatrical look. The background is a stark, absolute black void, making the figure emerge with volume. The clothing worn is an oil-painted interpretation of Victorian/early-industrial Dunwall-style attire—like the high-collared jackets and cravats of the referenced images, rendered with heavy, visible paint application that defines fabric and shadows. Any intricate details are painted with precision amidst the broad brushstrokes. This is a powerful, character-driven portrait that prioritizes brushwork texture, dramatic light, and a gritty, painterly finish to evoke the dark atmosphere of the character.

06 · BMW M4 print postergemini-3-pro-image-preview
Prompt

Create a premium editorial automotive poster inspired by a real printed magazine advertisement. Portrait layout, slightly angled physical poster on a rough concrete wall, subtle paper texture, natural shadows, realistic print grain, slight imperfections, folded edges, and authentic distressed typography. Center a glossy red BMW M4 Competition in a dramatic front three-quarter view, low angle, aggressive stance, realistic headlights turned on, deep black windows, carbon details, wet reflective ground, dark urban background collage, oversized bold ‘M4’ lettering behind the car, black/red/white color palette, Japanese-style vertical text accents, small performance spec block, barcode element, BMW branding, clean layout, high-end automotive editorial design, realistic photography look, not illustration, not cartoon, not 3D render, not AI-looking, ultra-detailed, sharp but natural, premium print advertising aesthetic, cinematic yet believable, professional graphic design composition.
