笔触涂鸦插画海报生成提示词

Transform the attached photo into a brush-painted illustration poster. The subject in the photo can be food, another product, a landscape, an animal, a person, or any object you want to feature as the main subject.
[Aspect Ratio]
Vertical 3:4
[Style]
Digital painting / brush-painted effect.
Visible brush strokes, uneven edges, slightly stretched paint marks.
Hand-painted appearance that feels untouched and authentic.
Interpret the image as a flat illustration with a simple arrangement of shapes rather than a realistic depiction.
No gradients, shadows, 3D rendering, or detailed textures. Keep everything completely flat.
Use a thin, irregular brush-painted outline that varies slightly from the painted areas.
[Color]
Background should be cream / off-white paper.
Use only 3–4 colors taken from the attached photo:
1 dark primary color
1 bright primary color
1–2 supporting colors
Slightly desaturated vintage tone.
Never increase the number of colors.
[Composition]
The subject should be large and centered, occupying approximately 50–55% of the canvas.
Extend the composition vertically with more space above and below, while also increasing the left and right margins.
At the top: place 1–2 English uppercase words describing the subject, in very large hand-painted brush lettering. Use very wide letter spacing; the text may wrap around the illustration or extend toward the right/downward.
At the bottom right: add a short handwritten English phrase of 3–5 words in an accent color.
[Text]
Look at the photo and choose suitable top and bottom phrases.
Do not use the actual subject name as the top text.
Choose words based on the atmosphere, location, season, time of day, or emotion shown in the photo.
The bottom phrase should feel casual, lighthearted, and slightly playful—not overly serious or explanatory.
[Forbidden]
Realistic rendering
3D
Shadows
Reflections
Logos
Watermarks
Border frames
Excessive enlargement of the subject
