used that bus stop window texture I'm becoming quite fond of, in luminosity mode at 25%; I also opened the Blending Options window for this layer and added a pattern overlay - bark - in luminosity mode at 25% - it gave it an interesting texture, like the photo is printed on painting canvas
then I ran a Diana/Holga action, did a little yellow oversaturation and then flattened those layers and slightly desat the entire shot.

finished off with an Alien Skin color film filter, settings to taste, resized and applied a slight pass of USM
