Looks very nice, the illusion is broken when you move the camera around, you really need a depth buffer perpendicular to water plane to figure out where the edges are, I have a much less good looking shader in Might is Right that simulates the shore-line (foam, whatever) - I use the inverse of terrain height-map to figure out where the shore is.
I get that that’s extra processing in general, so maybe not suitable for everyone.
Looks very lovely
