a snail survey team redrawing garden roads after a storm: places spiral signs around a puddle while a larva team verifies the route from above

Create a feature illustration for a nature-education workshop. The central event is a snail survey team redrawing garden roads after a storm at a school garden flooded after heavy rain, where the subject places spiral signs around a puddle while a larva team verifies the route from above. Use layered tracing paper, botanical rubbings, and low-saturation ink lines, with shadows caused by actual paper thickness; paper fiber, hand-torn edges, layered shadow, and negative-space relationships must remain clear and credible. Build the composition as a square centered composition broken by one action direction, with no decorative symbols crowded around the subject, output in 1:1. Action-related materials: liquid flow, wet marks, and condensation follow gravity and temperature difference. Treat the location light and color as charcoal, aged-paper beige, oxidized copper green, and low-luminance vermilion; light and dark emerge from layers and negative space in the chosen handmade medium, without plastic gloss or photographic flare. Action direction: Stage the action in two layers: show “places spiral signs around a puddle” clearly in the foreground, then use “a larva team verifies the route from above” in the middle plane as the consequence, with no unrelated event between them. Inside “a school garden flooded after heavy rain,” emphasize only “a snail survey team redrawing garden roads” and the connected actions “places spiral signs around a puddle” and “a larva team verifies the route from above”. Typography follows place no text, numerals, brands, signatures, or watermarks anywhere. Exclude template borders, unrelated icons, copied characters, garbled text, and brand symbols. Final art direction: original handmade mixed-media illustration with matte mineral pigments and visible paper fibers. Use this controlled palette as the dominant visual system: #D8C18E, #657A52, #6D6A63, #E6A07A; preserve believable local material colors within it. Keep any text absent or minimal unless the source brief explicitly requires it; never add logos, signatures, or watermarks. Keep one unmistakable primary subject or information route and one readable visual action. Use disciplined negative space and avoid default perfect symmetry. Physical credibility is mandatory: correct gravity, contact shadows, material thickness, tool weight, joint loading, fabric tension, liquid direction, reflections, scale, and occlusion. Create an original visual with no resemblance to a public figure, copyrighted character, existing campaign, or living artist signature style. No unrelated decorative icons, floating objects, duplicated limbs, plastic gloss, waxy skin, synthetic collage artifacts, or AI watermarks. Return exactly one finished image composed for 1:1; no variants, process sheet, split panels, mockup frame, or contact sheet.

这张图用于自然教育工作坊主题插画。主体为为暴雨后花园重画道路的蜗牛测绘队，位于暴雨后积水的学校花园，正在围绕积水放下螺旋形路标，幼虫队从高处校对路线。表现方式选择透明描图纸、植物拓印和低饱和墨线叠合，层间阴影由真实纸厚产生，验收重点是纸纤维、手撕边缘、叠层阴影和留白关系。使用 1:1；镜头结构为方形中心构图被一条动作方向打破，主体周围不堆装饰符号。与手部动作直接接触的材料必须满足液体流向、湿痕和冷凝遵循重力与温差。光线与配色：炭黑、旧纸米色、氧化铜绿和低亮朱红；亮暗由所选手工媒介的叠层和留白形成，不使用塑料高光或摄影光斑。动作层级：动作分层：前景清楚呈现「围绕积水放下螺旋形路标」，中景以「幼虫队从高处校对路线」交代结果，两层之间不插入其他事件。「暴雨后积水的学校花园」中只突出「为暴雨后花园重画道路的蜗」和动作「围绕积水放下螺旋形路标」「幼虫队从高处校对路线」。可见文字：画面完全无字，不出现数字、品牌、签名或水印。排除套模板边框、无关图标、复制角色、乱码和品牌符号。
