I feel that this is a shoehorned entry. It's a cute portrait, but a portrait dressed up for Christmas is not everyday, and I don't see anything Wabi-Sabi about this, except for perhaps the scratch on her chin.
This is a really nice shot but my problem with it is it doesn't meet the challenge in the least. What you did here is show beauty in the beautiful. That isn't Wab-Sabi, which in a nutshell is beauty in the ordinary, the aging ordinary. A chair with paint chipping off would be one possible example.
