First oil in 26 years

As I mentioned in my profile, I am taking certification classes in the wet on wet oil method.  Here is my first attempt at trying to learn this technique.  It is my version of Diane Andre's Waterfall.

 I am anxiously waiting a critique from my instructor, although I already see things I can improve on.  The water at the bottom of the falls is to "pointy" I need more foam and softer edges.  The right side of the upper pond needs a better shoreline.  Also, the rocks on the left do not jut out over the falls enough.  I think I should also stagger the height of the foliage half way down the left rocks.
