1{2 "提示": "Professional flat vector illustration in modern commercial style, depicting [SCENE_DESCRIPTION].\n\nPERSPECTIVE & COMPOSITION:\n- Extreme [ANGLE_TYPE] perspective from [STARTING_POINT] looking [VIEWING_DIRECTION] along ONE SINGLE [EXTENDING_OBJECT] toward [END_POINT]\n- [EXTENSION_DIRECTION_LAYOUT]\n- Single unified viewpoint with continuous depth progression following the SAME [EXTENDING_OBJECT] from [FRONT_END] to [BACK_END]\n- Dynamic [COMPOSITION_DIRECTION] composition with exaggerated perspective showing ONE continuous [EXTENDING_OBJECT] extending through entire frame creating sense of [MOTION_CHARACTERISTIC]\n- Seamless visual flow showing ONE SINGLE UNIFIED [EXTENDING_OBJECT]: [EXTENSION_DIRECTION_DESCRIPTION] - ALL PARTS OF THE SAME ONE [EXTENDING_OBJECT], NOT separate or duplicate [EXTENDING_OBJECT]\n- Smooth depth of field with natural foreground-to-background transition along the length of this SINGLE continuous [EXTENDING_OBJECT]\n- Clear visual leading lines following ONE [EXTENDING_OBJECT] creating strong unified depth within unified space\n- Balanced negative space with [SPATIAL_EMPHASIS_DIRECTION] emphasis suggesting [ACTION_CHARACTERISTIC]\n- Rule of thirds composition with emphasis on [CORE_FOCUS]\n- NO duplicate elements, NO multiple [EXTENDING_OBJECT], NO repeated objects - only ONE [EXTENDING_OBJECT], ONE [RELATED_OBJECT], ONE [MAIN_CHARACTER]\n\nCOLOR PALETTE:\n- [COLOR_TONE_DESCRIPTION] color scheme with [PRIMARY_COLOR_1_AND_APPLICATION], [PRIMARY_COLOR_2_AND_APPLICATION], [PRIMARY_COLOR_3_AND_APPLICATION], [SECONDARY_COLOR_1_AND_APPLICATION], [SECONDARY_COLOR_2_AND_APPLICATION], [ACCENT_COLOR_AND_APPLICATION]\n- [SATURATION_CHARACTERISTIC] colors [COLOR_EMOTION_DESCRIPTION]\n- [COLOR_STYLE_POSITIONING] color harmony [APPLICATION_SCENARIO_DESCRIPTION]\n\nSTYLE & TECHNIQUE:\n- Clean 2D flat vector illustration with minimalist approach\n- Simplified geometric character design and [ENVIRONMENT_ELEMENTS]\n- Crisp linework without heavy outlines\n- Flat color blocking with minimal gradients\n- Smooth depth transitions without layering artifacts showing ONE continuous [EXTENDING_OBJECT]\n- [SPECIAL_VISUAL_EFFECTS] integrated naturally\n- Strong perspective distortion on SINGLE [EXTENDING_OBJECT] length from foreground to background\n- Modern commercial illustration aesthetic similar to [REFERENCE_APPLICATION_SCENARIO]\n\nKEY ELEMENTS:\n- Complete [CHARACTER_TYPE] character in [CORE_ACTION_DESCRIPTION] in background [ACTION_DETAILS]\n- ONE SINGLE [EXTENDING_OBJECT] only: [FRONT_END_DESCRIPTION] in foreground, [MIDDLE_SECTION_DESCRIPTION] extending continuously through midground with dramatic foreshortening, [BACK_END_DESCRIPTION] in background\n- [RELATED_OBJECT] at/near the [POSITION] in foreground\n- Geometric [BACKGROUND_ENVIRONMENT] background with [ENVIRONMENT_DETAILS]\n- [DYNAMIC_EFFECT_ELEMENTS] suggesting [ACTION_CHARACTERISTIC]\n- Text \"[SLOGAN_TEXT]\" integrated along the [EXTENDING_OBJECT] trajectory with 3D perspective depth effect, bold modern typography\n- ALL elements are singular and unified - no duplicates\n\nMOOD & ATMOSPHERE:\n- [EMOTION_KEYWORD_1] and [EMOTION_KEYWORD_2]\n- Professional [FIELD_POSITIONING] quality [ATMOSPHERE_DESCRIPTION]\n- [SPECIAL_MOMENT_DESCRIPTION]\n- Dynamic EXTREME proportions emphasizing [EXAGGERATION_FOCUS]\n- Clean, polished, ready-for-publication finish with [ENERGY_CHARACTERISTIC]\n\nCRITICAL REQUIREMENTS:\n- Show ONLY ONE [EXTENDING_OBJECT] total in entire image\n- This single [EXTENDING_OBJECT] has [FRONT_END] in foreground, [MIDDLE_SECTION] in midground, [BACK_END] in background\n- NOT multiple [EXTENDING_OBJECT], NOT duplicate [EXTENDING_OBJECT], NOT separate [EXTENDING_OBJECT] pieces\n- ONE continuous unified [EXTENDING_OBJECT] object extending through perspective\n- ONE [RELATED_OBJECT] only at the [FRONT_END]\n- ONE [MAIN_CHARACTER] only in background\n- Avoid any visual duplication or repetition of elements\n- Each object appears exactly ONCE in the frame\n- Perspective makes the SAME [EXTENDING_OBJECT] look different sizes but it is still ONE [EXTENDING_OBJECT]\n- Maintain single continuous camera perspective throughout\n- Create STRONG depth progression with dramatic perspective FORESHORTENING along [EXTENDING_OBJECT] axis\n- All elements should feel part of one unified [ENVIRONMENT] environment\n- Ensure seamless integration of foreground and background within same spatial context"3}
