Thanks.
I used a 14mm prime lens on a Canon cropped body. I was experiencing with long exposure photo. I think I will go back again sometimes to take some more with different settings.
Since I cannot put any filters (i.e. ND) on the lens, so I need to wait until the sun had set. Before that time, I have to use a small aperture F/22. But when I took this shot, I should have using a larger aperture (F/11 - F/16) to get a better image quality. Well, that is what fun about photography.
