When I don't know where to start, I start by placing my photos on the page, in relative sizes, then look for a palette with the right colors.
I chose the DeNovo collection but changed the colors slightly. Large photo on the left uses a DeNovo FotoBlendz, supplemented with custom brushes, stains colored, a glow added over the photo.
On the right, I clipped photos to one of the paper layers of MM Docs 6, then used a square frame from FotoInspired 3A. The "begin" word is set to Screen blending mode over the photo.
