I'm certainly no expert, but I live in Cambridge so wanted to see
I like it for the most part. few things that I noticed (none of which are that big a deal):
- is the image completely level? I'm not sure...I feel like there's a slight tilt to the waterline.
- pp suggestion: some of the wispy clouds on the left, at least at this resolution, look like a hair on the lens or something. Might be worth removing.
- pp suggestion: the blue lights on the waterline provide an odd contrast to the rest of the image. maybe tone them down a little?
- I think it would work better for me if you cropped a small amount from the top, so the waterline was centered and the image was more panoramic
- maybe crop a little from the left, so the orange reflections provide a 'border' effect? not sure if that would work, but could be interesting.
anyway, it's a good image! Where'd you take it from?
