Spiral galaxy fine ink study
FinelinerMedium

One isolated tilted spiral galaxy with a bright oval core and broad curving spiral arms. Practice form, overlap and selective shading in black and gray marker.
Place the tilted central oval.
Sweep broad spiral arms outward from the core, following the same tilted plane.
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 arms on one shared tilted plane.
