A Year with my Camera!

My mono shot for this weeks exercise for 'A year with my Camera'

1/2 sec. f/4.5 30 mm ISO 100. I'm not happy with it, not crisp enough for one, what settings would have been better people? I didn't have the time to experiment further as the Antique shop was very busy at the time. I will keep on trying......my wife says I am very trying!!
