The layered triangles act like arrows, drawing attention to my photo. The cutaway portions of my photo bring the arrows in even further, making the photo truly a part of the triangle theme.
This same technique would work with circles and a circle punch, or even hearts and stars. Whatever shape you choose, don't be afraid to let it "cut in" to your photos.
