Just took a look at the card on the creator's website.
I think the Wheel associations are still there, but in a subtler, more associative form. It's almost like the image invites knowledge of Christian myth.
For instance, the birth of Jesus altered the fortunes of the world, so the baby on the card could be a symbol of the Wheel's possibility and renewal. The setting, which was the sole refuge Mary and Joseph found, was found by chance -- another reminder of the Wheel's association with chance, luck and fortune. The fire being lit by the wise man(?) could symbolize the transformative, purifying power of a new cycle, while the presence of the mother can suggest the most basic level of trust that's necessary for going in a completely new direction.
If you correlate the card with the Biblical narrative surrounding the scene portayed on the card, you'll come up with a lot more.
Lovely deck, btw. Congratulations on your acquisition!
