Use a wash-led drawing with broad transparent colour masses and sparse disconnected ink accents; let the washes establish form and place short ink fragments only at structural turns, with no complete black contour shell. A bag with its compartment open: a canvas messenger bag seen from the front with its flap folded open and a zipped inner pocket unzipped, showing a notebook, a pencil case, a folded map and a water bottle tucked inside, standing on a plain table, centred in a square.
Light: a soft daylight from the left, the bag in broad khaki and olive washes with warm shadow, the contents in small clear colour washes of red, blue and cream, a few short ink fragments at the buckles, zipper turns and the pencil case; palette of khaki, olive, red, blue and cream on open paper; light, orderly, quick.
Square 1:1 frame, centred composition with breathing room on all sides. No people, readable text, logos, brand marks, labels or tags on any object; surfaces are plain.
