The soft water look is done by shooting at a slower speed with your camera...I could give you my version of how to do this..but there are so many tutorials online...here is one link that I found quickly for yah!
I also process my images in length in photoshop after to increase the highlights and shading to give my image more "pop" but that is something you will learn over time as you evolve. I would work on the exposure and tripod work while out there shooting. Just need to be able to shoot in Manual mode so you can set the speed of your camera..but read that article or look at youtube. Lots of tutorials there!
