Greetings folks
I wanna share with you the drawing of a side view of an old man using Autodesk Sketchbook.
I started this drawing from the shading of the forehead then I proceeded to the shading of the nose to the mouth and jaw using hard airbrush, I moved to the shading of the hand and lastly the shading of the cloth using hard airbrush then I blended using smudge brush.
Below are the highlights

Your use of light and dark shades is lovely
Thank you @edbass
