Create a digital artwork inspired by the biblical verse 'Luke 6:39 - "And he spake a parable unto them, Can the blind lead the blind? Shall they not both fall into the ditch?"' Depict two ambling individuals wearing blindfolds, leading one another towards a ditch under a vast sky. Maintain a tinge of caution so as to reflect the verse's message. Consider a chiaroscuro technique to emphasise the light and dark, echoing the philosophical and spiritual concepts present in the parable.
