以粗獷塗鴉風線條描繪的表現系馬克筆插畫

Change the illustration style to a high-energy, marker-driven fusion of graffiti sketch aesthetics, manga exaggeration, and modern pop illustration. It relies on bold, sweeping linework with dramatic variation in thickness, moving from hairline flicks to heavy black brush-like strokes that carve out structure and attitude in a very instinctive way. Rather than carefully blended realism, the rendering is built through flat to lightly layered zones of saturated color—electric blue, violet, aqua, orange, peach, and neon accents—placed in graphic, almost impulsive shapes that suggest form through contrast more than smooth modeling. The alcohol marker technique shows up in the broad, juicy fills, translucent overlaps, and occasional streaky edge transitions where strokes visibly taper or feather, giving the image a fast, gestural sketchbook quality. Highlights are handled sparingly but strategically, with small opaque white marks and untouched paper areas used to create shine and visual snap. The style also incorporates loose calligraphic curls, scribbled contour lines, hatch-like texture marks, splatters, and accent strokes that sit partly outside the main form, making the piece feel spontaneous and performance-based rather than tightly controlled. Overall, it is a deliberately stylized, expressive approach that values movement, attitude, bold shape design, and vivid color impact over polished naturalism, combining raw marker spontaneity with highly intentional graphic composition.
