Alonso, at least on my system that image isn't popping up unless i dig out the URL from your post, and having done so, the water is definitely not sufficiently similar to warrant a post that is otherwise lacking critique or advice.
Frankie - if you can be bothered to find the image that Alonso tried to link, you'l see one thing they did that your image is moving TOWARD but has not yet achieved - which is water is one constantly distorting surface, rather than a flat surface with a variety of distortions popping out of it here and there. I'd continue working on eradicating those flat sections while you polish the tiling!
