Draw a circle.
We give the form rough tenches and we designate the middle of a leaf, where a big vein.
From above we define where will pass veins.
Also we connect to the main.
Let's begin shading with average tone.
Slightly pressing on a pencil, we will increase a tonality, will become a little more dark, or take softer pencil. Pritemnim a bottom of cabbage and from sides from the main vein, leaving white places.
Then we do transition to lighter tone.
From above cabbage hardly we touch with a pencil, strokes are hardly visible. For more contrast make a bottom of cabbage even more darkly. Drawing of cabbage is ready.
