As you might see, the pockets give our face the eyes. This particular face has a very content look about him. The butt crevice forms a nose while the edge of the butt cheek forms quite the wry smile. See below for further examples.
Keep in mind there are many variants and forms out there and each one is unique in its own special way.
Try using the techniques we've learned on the images below without my help this time.
