Binoculars fine ink study
FinelinerChallenging

One compact camera in three-quarter view, box body, central cylindrical lens and top shutter button; no brand or lettering. Practice structure, perspective and developed values in fine ink.
Block in the box with a visible top and side.
Build the lens from concentric ellipses and add the shutter button.
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 lens ellipses aligned with the front face.
