An afternoon in Cambridge

I joined a Camera Club trip to Cambridge shooting a series of prescribed subjects; I found this challenging and fun. Particularly "Motion" for which I failed to get any shots within the rules, though this composite pleased me after a little work in Photoshop

I'm not sure whether this is "predominantly one colour" or "a familiar object from an unusual angle" but Ann Miles' pictures (see link) of trains at Royston and Paddington rang some of the same bells!
