There are no special techniques here. After selecting the background, I selected the mask and applied the photo, added two skyline overlays behind the mask and lined them up with the photo, added the 3 brushes behind the mask, then added the word art in Pin Light blending mode and the title.
Created with ET Designs "URBAN AUTUMN"
Background from Lynne Anzelc's "COUNTRYSIDE"
