Hippo Smiles Adding Complexity to Simple Coloring Book Pages

Adding lines to kids coloring book pages adds interest and movement to the page.  With a blue ball point pen I added entering and exiting swirling lines.  Then colored the hippos background with a muted set of pinks and purples.  The smiling hippo herself got the lighter set of pinks and purples with hopes that it would pop her off the page a little bit.
