There are a couple interesting things about this card. First off, there are two figures walking towards the Sun, not just one. Does this mean that Opportunity is meant to be shared, or that the Opportunity IS the sharing? They are hand in hand, in any case.
Also, one of the figures is looking backwards. Why? Is he looking at the viewer, inviting them to join? (What a wierd little threesome.) Or, is he taking a last look behind them as they move forward into whatever lies beyond the hills?
