折纸水库剖面，纸水压着村屋

A 16:9 paper-craft diorama of a hillside reservoir, shown as a side-on cutaway. At the left, a block of blue water, two thirds of the picture wide, is dammed by a curved wall of stacked pale cream modules. A low pipe leaves the base of the wall through a small grille and travels right and downhill to a huddle of tiny paper roofs in terracotta. Over the top of the wall, a separate slim spillway of white modules steps down the outer face and drops into a paper stream edged with stone. Green slopes of folded modules rise behind everything. Dam and water sit mid-frame; the pipe is the leading line pulling the eye toward the lower right. Construction rules: every object is assembled from repeated folded-paper units of the same scale, and their geometry and joins stay visible, with the unit's orientation and colour doing the work of the large shapes. Keep to big shapes: silhouette, pose, proportion and broad colour areas. At anything smaller than a fingertip, use only folds, creases and paper relief, so every surface is translated into folded paper. If eyes or a nose were present they would be paper shapes carrying one paper-made highlight. Paper fibre and crease texture are visible throughout; no photographic detail, printed outlines, photo scraps or text, and no labels or lettering on the model. Colour and light: the dam in pale cream, the water in deep blue and light blue, hillside in olive and green. One soft light from the upper left throws a small crisp shadow off each fold.
