Lunar crater marker study

One isolated bowl-shaped lunar crater in oblique view, an oval raised rim and recessed floor, no landscape beyond a small local ground patch. Practice structure, perspective and developed values in black and gray marker.

A way into the drawing

1. Establish the main shapes

   Set the outer crater ellipse and smaller floor ellipse.

2. Connect the structure

   Connect the rim slopes to the recessed floor.

3. Develop the drawing

   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 tryMake the far inner wall visible above the crater floor.
