The image of couple is fairly good, I like how you've incorporate the colors into the scan as oppose to vectoring it (by the way the link to your original image is not working). I don't think the image on the left works, point one: their at an indoor burger joint which is clearly emphasized by the setting so that lovely outdoor restaurant doesn't work for me, it's more like a contrast.
However I find that either setting/atmosphere works well for the couple plus, I like that you kept the colors neutral. That subtle heart/glittery design is quite beautiful. I'm more drawn to the right side of the wallpaper but I wish I could like it as a whole.
