We were lucky enough to visit Rome in 2014, love the architecture there......

Distressed Edge Overlays No 9 http://www.oscraps.com/shop/Distressed-Edge-No.-9-Overlays.html
I duplicated my photo and on the bottom one used Filters - Find Edges and I emphasised the contrast with Levels. I used an artistic filter on the top copy with Poster Edges. I used reverse masking (Alt+ layer mask icon) on both photo layers, which gives a black mask, then using brushes and colour white and making sure I was on the mask layer, I painted on the areas I wanted to show as sketch and those I wanted to be the darker top photo. I imported two background papers and set the blending mode to Linear Burn on the top copy to merge them together. Various transfers were moved around above and below the photos. I added the frame a title and the Distressed Edge Overlay to finish.
