6 in cambridge.
One of the most beautiful cities - full stop.
I'd say you either need to give them more exp, or more wellie in pp, they all coming across as a long way under. I notice at least two were taken at 30sec, so there's scope for upping that if you have remote, and as you took them at 100iso there's plenty of head room to boost the image in pp which will give just as good a result as had you upped the iso on location.
I'd also go for more classic subjects, seeing as the city is bursting with them. The college porters didn't like the idea of my tripod leg straying onto their curtilage when I was last there, but there's no need.
