This is a single shot, single exposure and not a composite of any kind. You can have fun and try to reconstruct the scene. The shot is made in diagonal, partly through the corner of a theater glass building, so it is a combo of direct view, transparency and reflection.
Oh yes - this is so very good - it is so strange that our cameras can pick up and combine images that our eyes only vaguely detect - or does our brain purposefully make us focus on the main point of interest? :0
