Human ear fine ink study
FinelinerChallenging

One complete adult running in side view, one knee lifted, opposite arm forward, both feet visible, simple sports clothing. Practice form, overlap and selective shading in fine ink.
Map the torso lean and alternating arm and leg directions.
Connect the elbows, knees and feet through clear bends.
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 opposite arm and knee moving forward together.
