Show us the picture. It's probably overexposed but maybe it's properly exposed and you're not used to that. 15 seconds is a pretty long exposure time.

Your camera does not know what effect you want it will try and adjust for a normal exposure. You don't say what aperture but 15s at ISO800 would over expose a city street, if you were anywhere dark but with a city nearby the sky would not be black - probably a mixture of dark blue and orange.

You need to set your camera as a "Night Shot" or take control and adjust the camrea's settings for the result you want.

It looks like late evening judging by the street lights. To make it look like night you could just PP this shot, darken and apply a cooling filter, or re-take at a 5-8sec exposure or drop ISO800 to ISO400 keeping to 15 seconds. The camrea has done a remarkable job in giving you a "technically correct" exposure, a pitty that was not what you wanted.:(

15s was just too long & ISO800 was too high.

in a shot like this, i would have tried Av to choose the aperture and let the camera choose the shutter speed. I would have also used a tripod/solid surface to stand camera. once you have the camera stable, you could have left the ISO low to avoid the noise.
