Spiral galaxy fine ink study
FinelinerMedium

One crescent moon with a few broad shallow crater marks, no face, stars or scenery. Practice structure, perspective and developed values in fine ink.
Draw the outer moon curve and inner crescent edge.
Place a few broad crater ovals along the visible surface.
Resolve the connected planes and overlaps, then build layered details and a full range of local values. Preserve clear paper highlights.
A small thing to tryKeep the two crescent tips joined to the outer curve.
