The description of cherubim as they appear in heaven is very different to the way they are portrayed in art. Ezekiel’s description of the living creatures (Chayot) he later calls cherubim is very similar to John’s description of the living creatures (Zoa in Greek), except that the beings John saw had 6 wings. (Rev 4:6-8)
Based on the description in Ezekiel each of them had four wings, two wings covering its body and the other stretched out straight, one toward another. Under their wings on their four sides they had human hands.
