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.
