can't access your photo site also. As most mentioned, you will need to check the focus is correct or not, then can try shooting at Apperture mode at f/8, and keep ISO low like 100 or 200 to reduce noice. If you like it brighter or darker, just adjust exposure accordingly.
happened to me before. took me 3 weekends of attempts before i realised my stupid mistake.
1. focus on the distant buildings. (this i got it right)
2. use f/11, good enough. (this i got it ok)
3. use 15 seconds, dont over expose your photos (this i found to be the producing the best looking pics)
4. use ISO 100. (this i got it terribly wrong, photos all turned out like what you had)
In the pic OOF is not the worst. I feel that the noise is more of a issue than anything else. Use the lowest ISO setting will prolly improve the pic. Adjust the F number till you get a satisfactory pic.
