Not everyone can be a saint and have all the virtues. But many of us have some pieces of segments of a saint in us. We are flawed, but we have some virtues, though not all of them. This is an ordinary human like you and me.
This image is inspired by the gold ground Renaissance religious paintings. As you can see, the nimbus (halo) behind Robert's head is partly covered by the curtain. This incomplete halo symbolizes Robert's real identity as an ordinary human as you and me instead of a Saint who is flawless.
