Spiral galaxy fine ink study
FinelinerMedium

One irregular meteorite fragment in three-quarter view, faceted rocky volume with a few broad shallow pits. Practice structure, perspective and developed values in fine ink.
Draw the uneven outer mass and main plane changes.
Place shallow pits on the visible planes.
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 tryUse the large planes to explain the volume before adding pits.
