What I like about this abstract is the clartity of the water falling over the small breakwater (it reminded me of dentures, hence the title. What I am not sure about is that there isn't a point of reference or an object to grab your attention. Being an abstract, does it need a reference point or objecct to draw in your attention?
I just used one of the Lightroom presets and then tweaked it from there. Unlike many others, I am not a fan of B&W. I think it just worked for this image.
