Tricycle fine ink study
FinelinerMedium

One folded paper airplane in three-quarter view, pointed nose, central fold and two coherent triangular wings. Practice clear contours and a few local shadows in fine ink.
Map the nose and central fold axis.
Extend two folded wing planes from the center.
Refine the clear outer contour, add only the most useful interior details and place a few small local shadows. Leave most of the paper open.
A small thing to tryKeep the wing edges converging toward the same nose.
