Wings on angels in artwork are a symbolic representation of their spiritual nature and their ability to travel between the presence of God and man. Cherubs as either chubbie babies (Cupids) or just the baby heads with wings are a common motif in Renaissance and Rocco Art.
I substituted a baby-face for Grinch's head to turn him into an angel. No, it isn't Biblically correct or doctrinal. It was supposed to be fun.
