Step 5 Select the Ellipse tool (L) and draw the eye. Start with the pupil, set to black fill and no stroke. Copy and paste this shape behind (Cmd/Ctrl + B). Using the Selection tool (V), press Shift and drag this shape larger and add a white fill. Draw another circle for a highlight and copy and paste the eye to adjust it according to your sketch.
Step 6 Draw the rest of your character using the Pen tool (P). Draw one arm and then copy/paste/reflect as we did in step 4. Give these the same fill the doughnut shape, using the Eye Dropper tool (I). Now copy and paste your doughnut in front and move it so it overlaps with the arm shape, then press Alt +Click to select interest shape area.
Step 7 Repeat this process to create the legs. Apply a Multiply blend mode to them with a15% Opacity. Select the legs, then go to Effect > Blur > Gaussian Blur. This helps blend the shadows to stop them looking so harsh. This is a great way of blending colours without using a gradient, since they can be a little hard to control at times.
