بوستر يبرز التباين بين شخصيات حقيقية وبيئة مرسومة يدوياً بألوان أحادية

Please make the photo I uploaded into a 3:4 vertical "Original Photography at the top / Line Art Translation at the bottom" comparison poster.

**[Keep the Subject Realistic]**

The people in the photo always maintain a complete photo-level realistic effect. Facial features, skin tone, hairstyle, hair color, expressions, movements, clothing, accessories, and body proportions are all taken from the original photo—do not redraw, do not change clothes, do not change movements, do not add or subtract people, and do not have missing limbs.

The image continues to use the original photo's framing, cropping range, lens angle, person size, and location—do not mirror, do not re-center, do not scale randomly, and do not create new movements for the person. The person always stays in their original position as the real visual subject of the image. Important objects the person is holding or using can continue to retain the photo texture.

**[Convert Environment into Hand-drawn World]**

In the bottom half, the environment around the person completely breaks away from the photographic texture and shifts to a soft warm-white paper background.

Buildings, trees, mountains, walls, doors/windows, curtains, furniture, books, plants, lamps, carpets, photo frames, and other background objects are all simplified based on the position and proportions of the original photo, redrawn with loose, generalized monochromatic lines.

There is no need to copy all real details; only keep the main outlines, size relationships, and spatial positions that allow the scene to be identified. Remove the original background colors, real shadows, photographic textures, and material expressions.

**[Monochromatic Line Rules]**

The entire environment in the bottom half only allows the use of **one saturated monochromatic ink line**.

Prioritize extracting an obvious non-neutral color from the original photo, then adjust it to a clear, bright, medium-saturation color. If the original image is generally grey, white, or has no obvious primary color, automatically choose an accent color that coordinates with the image, such as cobalt blue, brick red, coral red, forest green, deep cyan, purple, wine red, ochre orange, etc.

One image can only have one line art color; mixing a second color is not allowed.

The line texture should not be like a fine pen drawing, nor like a pencil sketch, but closer to the **casual drawing feel between a medium marker and a ballpoint pen**: lines can shake slightly, thickness and pressure can vary slightly, turns do not have to be perfectly accurate, connections can be slightly misaligned, and line ends are allowed to slightly overshoot, giving an overall natural feel of being drawn in one go.

Outlines should not be too neat; they should retain a bit of clumsiness, imperfection, and spontaneity.

Objects should be summarized with simple shapes as much as possible:

Books are represented by simple rectangles;

Plants are represented by several groups of loose leaves;

Lamps are represented by simple domes and supports;

Windows only keep the basic frame;

Fabric only has a few sparse folds drawn.

Do not strive to fill the whole drawing; retain a large amount of warm-white negative space to make the image relaxed, breathable, and have a bit of an unfinished manuscript feel.

**[Ground and Space Treatment]**

The ground, roads, tabletops, wall corners, countertops, etc., only keep the most basic outer outlines and a few structural seam lines.

Do not use a grey base, do not draw real shadows, do not fill large areas with color, and do not create 3D light and shadow. All environmental elements always use the same ink color, letting the photo-realistic person naturally overlap on top of the monochromatic hand-drawn environment.

**[Overall Visual Direction]**

The final effect should present a clear **"Realistic Subject × Coarse Monochromatic Hand-drawn Environment"** contrast.

Overall temperament leanings:

**Editorial collage, independent magazine lifestyle illustration, simple environmental graffiti, clean warm-white paper, minimalist, interesting, relaxed.**

The bottom half is not a refined illustration, but a generalized monochromatic background manuscript with human traces.

**[Prohibited]**

Do not draw real people as illustrations or cartoons;

Do not change the person's identity, face, clothing, and posture;

Do not add extra people;

Do not have missing hands/feet or limb errors;

Do not add important objects out of thin air that do not exist in the original image;

Do not use multi-color line art;

Do not retain realistic photographic backgrounds;

Do not do gradients, watercolors, 3D, anime, manga, or refined vector illustrations;

Do not add text, logos, watermarks, interface elements, or any UI.
