Style prompt guide

Style traits to keep

A miniature ancient harbor town takes shape on an unrolled parchment plan, with tiny ochre-clad workers rolling limestone blocks toward an unfinished quay. GPT Image 2.5 Sunburst handles it well because the prompt names exact materials, colors and a camera style, so the result reads as a real handmade diorama and not a flat illustration.

This style is a handmade tabletop miniature photographed up close. Its look comes from natural materials, warm light and a small color contrast.

Palette
Cream, ochre, limestone and coral dominate, with cobalt as the one cool accent. This limited, warm range makes the boats stand out and keeps the scene harmonious.
Texture
Clay roofs, paper fibers, wooden rollers and resin water each have a different surface. Showing these differences is what makes the scene feel handmade and physical.
Light
A warm desk lamp gives a soft glow and short shadows. It suggests a craftsperson's workbench and adds depth between the blocks, figures and parchment.
Composition
The vertical 4:5 frame stacks the parchment, the building site and the inlet at the edge. Macro framing keeps tiny workers large enough to read, with a soft background.

What defines this look

  1. Scene and baseA miniature ancient harbor town is being assembled directly on an unrolled cream parchment plan

    Sets the subject and the surface it sits on. 'Being assembled' gives the scene a work-in-progress feel. If you drop 'parchment plan', the town loses its drawn-map base and floats on a generic table.

  2. Action and figurestiny workers in ochre tunics guiding limestone blocks along wooden rollers toward a half built quay

    Gives the scene a story: small figures, one clear task and a visible goal. The ochre and limestone add warm earthy tones. Remove it and you get a still, empty model town.

  3. Cool color accentSmall cobalt boats float in a shallow resin inlet at the page edge.

    Cobalt boats and a glossy resin inlet add the only cool, shiny area in a warm scene. Without them the image becomes one beige and orange mass with no focal contrast.

  4. Light and cameraWarm desk lamp illumination, macro physical diorama photography

    The lamp creates soft warm light and gentle shadows, while 'macro physical diorama photography' gives shallow depth of field and a real-object look. Change it to 'studio light' and the mood cools and flattens.

  5. Texture and moodcoral clay roofs and visible paper fibers, industrious inviting craftsmanship, no text.

    Coral clay and paper fibers push the model toward tactile surfaces. 'Industrious inviting craftsmanship' sets a friendly mood, and 'no text' keeps stray lettering off the plan.

Same style, new subjects

Potter at the wheel

Applies the same diorama style to a single adult craftsperson, good for a portrait-style focus.

Prompt

Vertical 4:5 portrait frame. A miniature potter's workshop is being assembled directly on an unrolled cream parchment plan, with a tiny woman in an ochre apron shaping a clay jar beside a half built kiln. Small cobalt bowls dry on a resin shelf at the page edge. Warm desk lamp illumination, macro physical diorama photography, coral clay roofs and visible paper fibers, industrious inviting craftsmanship, no text.

Hilltop village street

Moves the style to a city street scene with steps and stalls.

Prompt

Vertical 4:5 portrait frame. A miniature hillside village street is being assembled directly on an unrolled cream parchment plan, with tiny market sellers in ochre cloaks carrying limestone baskets up stone steps toward a half built bell tower. Small cobalt awnings shade stalls beside a shallow resin fountain at the page edge. Warm desk lamp illumination, macro physical diorama photography, coral clay roofs and visible paper fibers, industrious inviting craftsmanship, no text.

Cat on the build site

Adds a pet as the large subject while keeping the miniature world around it.

Prompt

Vertical 4:5 portrait frame. A miniature ancient harbor town is being assembled directly on an unrolled cream parchment plan, with a small orange tabby cat sitting beside a half built quay while tiny workers in ochre tunics stack limestone blocks around it. Small cobalt boats float in a shallow resin inlet at the page edge. Warm desk lamp illumination, macro physical diorama photography, coral clay roofs and visible paper fibers, inviting craftsmanship, no text.

Model and settings

Keep the 4:5 ratio, since the vertical frame suits a stacked scene of plan, quay and inlet, and it works well for portrait posts. Keep quality on high, because the fine details of paper fibers, clay roofs and tiny workers depend on it. For a wide harbor panorama, switch to a landscape ratio and describe more boats and buildings. For a quick test of composition, a lower quality setting is enough before a final high run.

  • Seedream 5.0 ProChoose it when you want even finer miniature detail, or when you have reference pictures of real clay, paper or harbor models to match.
  • FLUX.2 ProA good pick if you want a more photoreal macro look, or tighter control of the ochre, coral and cobalt colors through exact hex values.

When the style drifts

The style turns into a flat illustration or CGI render instead of a physical diorama.
Keep 'macro physical diorama photography' and add 'shallow depth of field, real clay and paper surfaces, no digital render look'.
The tiny workers become blurry or merge into the blocks.
Reduce the crowd: write 'four tiny workers' and keep quality on high so each figure stays distinct.
Colors turn muddy, with the cobalt boats lost in orange tones.
Name the accent again, such as 'bright cobalt boats against cream parchment', and say 'soft lamp light, no heavy orange cast'.
Fake lettering or map labels appear on the parchment plan.
Keep 'no text' at the end and add 'blank parchment with only faint ink lines' so the plan stays unlabeled.

Questions about this style prompt

How do I make an AI image look like a real handmade miniature?

Name the materials (clay, resin, paper fibers), use 'macro physical diorama photography' and give a single light source such as a desk lamp. These cues make the model show texture and shallow depth of field.

Why does this prompt include the words 'no text'?

A parchment plan invites the model to add map labels or writing. GPT Image 2.5 Sunburst renders text cleanly, so it may add some unless told not to. 'No text' keeps the plan blank and the scene focused.

Can I change the harbor to another place and keep the look?

Yes. Swap the town, workers and goal, such as a mill or a bridge, but keep the parchment base, lamp light, macro wording and material list. Those parts carry the style, while the subject is easy to replace.
