I really like your choice of background paper. The zigzag paper not only provides a great pop of color but also has the feel of butterflies flitting around the yard.

Usually butterflies are celebrated for their color so I think it is great that you turned the photos blacka nd white. Your colorful layering is lovely and yiu made a great title (love the font).
