It's a Christmas Tree! If you want a narrower tree, or a more gradually sloping tree you could play with the size of the photos- but overall you get the idea. Just be sure to add some fun embellishments like a trunk and a star to finish off the look.
I used the fun new Jolly Holiday DSP for this page and then "distressed" the edge of my layout with the textured stamp. Add some journalling and some embellishments, and then the page is complete!
