It's just something I made in Photoshop this morning after coming back from a trip to a nearby beach. I have to get the shadows the right colour and more realistic looking. I keep meaning to take a photo of that building when I'm down there but I never have a camera with me but this morning it was in my car.
None of the other shadows are soft so I'm going to have to figure out how the cutouts in the building would look in real life and make nice sharp shadows with a blue-ish tinge.
