Odd location for such a transport, but that's the appeal of it. The edges around the people are noticeable in a way that I don't think helps the overall image, though - I would have preferred to be left thinking the two were actually there in that setting.
This has a wicked edge to it (as in "edge", not some sort of physical boundary or photographic blending point) and a kind of lurid paperback novel quality to it. Not sure whether you'll find that good or bad.
Sorry but the image quality of the photo of the couple is just dreadful, was that image taken on a camera phone? It just makes these two images blend together rather badly, the blur on the rim where the two images intersect is also a dead giveaway, try to stay clear of that in the future.
To me, with the woman's eyes wide open like they are it looks kind of like she's dead. Which would then in turn makes me view your image as disturbing. Hmmm, just my take on it. I do like the lines of the building in the background though.
