하천정화 전단

Design an environmental flyer image centered on volunteers collecting litter beside a clear river, with reusable gloves, sorting bags, reeds, and a bright tree-lined bank. Use a bold editorial poster layout with teal water, leaf green, sunlit yellow, and coral accents, strong visual hierarchy, crisp shapes, and a slightly elevated view. Reserve clean empty space for later copy while showing the action clearly. No text, no watermark.
