I like #3. I can see this being quite nice with a little more PP. It bugs me that you cannot see what the lighthouse is connected to in 1 and that the lines direct your eyes right off the photo in 2. The last two seem more like 'hey, Ive just found out how to take long exposures of water!' instead of 'hey, look at these awesome long-exposure shots of water!'
Keep shooting! :thumbsup:
My rendition of #3. I may have changed the mood a bit, but I like the way it turned out. Selective levels, curves, saturation. I think I may have punched the colors a bit too much..not sure..
