Process: I started with to placed the photos and changed the blending mode for the right one to Darken. I added a mask to the photo of ABBA and erased parts of it. I also added some adjustment layers. I placed brushes from Theater No 1, Theater No 2 and Music Notes No 2. I finished the layout with two transfers from ArtsyTransfers Paraiso with a decreased opacity.
