Thank you all for all the comments and encouragement. First of all I'd like to apologize replying this posting in English. I speak Chinese just an unfortunate I don't read and write Chinese; I know it's a shame

I had this pictures posted in Chinese by the help of a very good friend of mine as well as my photography mentor. So sorry if I ever mislead you guys.
@农夫甲, I didn't know either if Laguna beach have this scenery not unitl I was told by my buddy (who like fishing) Take Tan that it has this tower. It was located in at the south side of the park. To be exact it was at the end of the road named Sunset avenue or road. Anyway you could check it out in google maps. The first picture was taken using B+W ND10 filter for about 2 minutes exposure. I want to create a smooth cotton feeling of the wave.
@frankL6, thank you for constructive comment. I guess there are not much colors in original pictures for me to play around with. I shot this scene in the early morning and it was so foggy and gary. The color pictures was so flat and gray due to not enough sunlight. You're right in suggesting more of the contrast and tonal differences. I did applied your suggestion in my workflow on the same pictures and they were great and better tonal contrast and also made the pictures feel like have more weight to it. Thank you.
