In Photoshop I used the quick selection tool to focus one part of the photo. I also used liquidity tool and perspective so it makes it look in place. The building in the background was not actually there i had to but it under the background. Using the layers to put things in perspective. I used a distort tool to make the graffiti look like it is a part of the building. I also changed the colour of the graffiti so it blends in with the building so it does not look fake. I had some trouble finding my edit :(
