I believe the faces of the creature may represent the different parts of God's creation as holiness illustrated. Soul of Man, Heart of a Lion, Strength of an Ox, Mind of an Eagle. I'm curious what the wings and wheels may signify?
10As for the form of their faces, each had the face of a man; all four had the face of a lion on the right and the face of a bull on the left, and all four had the face of an eagle. 11Such were their faces. Their wings were spread out above; each had two touching another being, and two covering their bodies. Ezekiel 1:10-11

Moses was a hundred and twenty years old when he died, yet his eyes were not weak nor his strength gone. Deuteronomy 34:7
