日系稚拙萌系粗糙动漫涂鸦提示词

Overall Style:
An extremely casual, rough, and childish Japanese-style cute anime character digital doodle, appearing as if quickly drawn with rough crayons and markers in common painting software. Retain the original character's recognizability, hairstyle, hair color, facial features, clothing, accessories, and iconic expressions.

Line Art:

* Use obvious black rough strokes to outline the character.
* Line thickness is extremely uneven, with some parts suddenly thickening and others breaking.
* Outlines are loose, inaccurate, and slightly skewed.
* Lines have a distinct hand-drawn grainy and smudged feel.
* Do not strive for precise strokes; allow lines to be misaligned, overlapping, and incomplete.
* Prohibit fine and smooth vector line art.

Coloring:

* Use large areas of opaque simple flat colors.
* Colors slightly overflow the outlines, allowing for unpainted areas and white gaps.
* Shadows use a small amount of rough gray or dark strokes in the same color family.
* Highlights use casually smudged short white strokes.
* Retain the rough texture of mixed crayons, pastels, and markers.
* Do not use complex gradients, fine light and shadow, or rich color layers.

Facial Features:

* Retain the original character's eye color, eye shape, and iconic expression.
* Facial features are appropriately simplified; eyes are represented with thick black lines and simple color blocks.
* The mouth should be as simple as possible; the nose can be omitted.
* A small amount of casual pink blush strokes can be added to the face.
* The expression retains the original character's characteristics; do not change the personality or temperament without authorization.

Hair and Clothing:

* Fully retain the original character's most recognizable hairstyle and hair color.
* Hair consists of several large color blocks; do not draw many fine strands of hair.
* Clothing retains the original color, outline, and iconic accessories.
* Clothing folds and decorations are highly simplified.
* Do not change clothing or add accessories not present in the original image without authorization.

Composition:

* 1:1 square canvas.
* Character bust, with a slightly larger head proportion.
* Character is centered, retaining natural white space.
* Pure white background, no text, complex scenes, or decorative borders.

Most Important Style Constraints:
The image must be rough, sloppy, simple, and childish, like a cute anime doodle drawn casually, rather than a refined illustration intentionally mimicking a sketch.

Prohibit automatic refinement, prohibit fine line art, prohibit complex hair structures, prohibit delicate gradients, prohibit 3D effects, prohibit excessive light and shadow, prohibit adding complex clothing details.

Final Effect: Low completion, thick black outlines, large flat color blocks, casual white highlights, Japanese anime digital doodle with obvious crayon grain.
