I used the Santa's Coming collection by Neia Scraps! https://store.gingerscraps.net/Santa-s-Coming-bundle-By-Neia-Scraps.html
Great photo! I can really see the joy in the kids faces. I like the Santa cluster and your choice of papers. The title work is great too.
This photo should be treasured now while you can still dress the kids in matching jammies:) I love the large cluster with the snowflake and the flags placed around the round shape. Love the mix of font/alpha you used for the title.
