Tricycle fine ink study
FinelinerMedium

One empty wooden rowboat in three-quarter view, tapered hull, open interior and cross benches, no oars or water. Practice form, overlap and selective shading in black and gray marker.
Set the pointed hull outline and open rim.
Join the inner hull and cross benches, keeping their ends on the same rim perspective.
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 seats spanning the boat interior rather than floating above it.
