Spiral galaxy fine ink study
FinelinerMedium

One compact orbital satellite in three-quarter view, central box body, two rectangular solar panels and a small dish antenna. Practice form, overlap and selective shading in fine ink.
Construct the central box and two panel planes.
Join both panels with short arms and attach the dish.
Use selective interior marks and local shadow groups to explain the overlaps. Keep the lighter planes open rather than shading every surface.
A small thing to tryKeep the panels attached to opposite sides of the body.
