Airplanes: learn to draw 5 subjects

Learn to draw biplane, helicopter, hot air balloon, jet airliner, pilot in five easy steps each. Every subject starts from a few simple shapes and grows line by line into the finished drawing; the app lays the steps out with arrows between them and an empty box to draw in. Same friendly style as the Airplanes colouring pages and elements, so a whole book feels like one world.
