Create a horizontal 4:3 architectural study of the Old Bridge in Mostar on warm cream graph paper. Use delicate hand drawn graphite and brown black ink lines over a fine, even square drafting grid. An elevated isometric view shows the bridge extending diagonally from a dense cluster of stone buildings at the upper left toward a second cluster at the lower right. The great single stone arch is the central focal point, with its full curve and the riverbank below clearly visible. Retain a generous paper margin around all buildings and labels.
Draw blocky watchtowers at both ends, pitched roofs, small windows, irregular masonry courses, steep access paths and projecting terraces. Thin parallel lines describe the bridge walkway and parapets. Light crosshatching models the underside of the arch and shaded tower walls, while the main surfaces remain mostly the color of the paper. A few faint contour lines indicate the river and exposed rock; do not fill the river with blue paint.
Place small uppercase architectural labels outside the drawing, connected with fine leader lines. Use “STONE BUILDINGS”, “WATCHTOWER (LEFT)”, “STONE ARCH BRIDGE”, “FLAGS”, “WATCHTOWER (RIGHT)”, “RIVER NERETVA” and “CAFE TERRACE”. Keep label sizes consistent and avoid overlap with the structure. Slight aged paper variation, precise but human linework, no large title, rendered shadows, photograph fragments or interface.
