You've managed to make this photo look about 40 years old which, if it was intended, is fitting for the building shown.

Serendipity is a difficult concept to visualize. For me it means being at the right place, at the right time, and being lucky enough to capture something unique. Some of these entries are set up shots trying to illustrate that concept, and some record a serendipitous moment experienced by the photographer themselves. This is an example of the latter. Decent enough shot, but nothing really exceptional. Doesn't really say serendipity to me.
