Step 1:

    To start with draw four different sized oval shapes and place them like in the sample below.

    Step 2:

    Now add four long vertical rectangles like in the sample below.  This will give us the basic guide for our piglet.

    Step 3:

    Now using our guide from step 2 we need to give our pig some features and also draw in the actual outline of the pig like below.

    Step 4:

    Now draw around the outline in a darker tone and remove all unwanted marks leaving you with a clean image.

    Step 5:

    Your now ready to add some shading to your drawing like below.
