I have no experience of night photography so I was pleased that some of my shots came out. I had a few problems with my camera and landed up swapping bodies and lenses and wasted a lot of time fiddling about - the problems were pilot error! There was nothing wrong with my camera. Oh well, I think I shall have to go and do a course as I have only learnt to use my camera by trial and error which is probably not the way to do it. I don't have problems with bird photography so perhaps I should stick with that.
Lovely night shot of the city scape. I hope you don't mind me mentioning but my eye is distracted by the square at the bottom RHS of the shot - I think I would have cropped it out. There is also a dust bunny top RHS - I hope it's on your lens and not your sensor.
