Nikon D5200, Sigma DC 18-250mm 1:3.5-6.3 Macro HSM lens taken at 18mm, f/8.0, 30 seconds, ISO 100.

My first attempt at long exposure. I purchased my first DSLR about a month ago, so still learning the basics. I accidently left Vibration Reduction switched on on the lens, which I understand is a mistake when on a tripod.

I would be interested in any feedback on how I could have improved this shot.
