Tushit, ref your printing question, I do think you could stand to do some unsharp mask on this, as well as a bit of contrasting. Also, there's some rather large dust spots that could use cloning, in the sky on either side of the lighthouse.
The only blur you should see in a print on this is to the tree on the right, where it was blowing in the wind during the long exposure. Otherwise, you should be able to get a good print out of this.
