This is a drawing from two years ago that I never uploaded. I was waiting to digitally color the piece, but I think it stands on its own as well.
The sheep represent three different responses to the wisdom, guidance, and friendship of the shepherd. The sheep on the lower right looks away, its face (and sight) shrouded in darkness. The sheep in the rear sees the shepherd but remains at a distance, perhaps judging itself unworthy of his company.
The sheep on the left stretches upward to make contact with the shepherd. The boy in turn lowers his hand, meeting it halfway. He sits far above all three sheep, watching over them with equal care.
I think we all have that inner voice that tries to steer us in the best direction. Call it the conscience, the superego, the higher self, or whatever you like. No matter how many times we make mistakes, we can still turn to the compass within and choose a better path.
