I think that is seriously getting there. I lke the way you've handled the shore water height.
There's a general rule of thumb that I read in some wave simulation papers I've found, that state that the wave height is approximately 1/7th of the distance between caps. Which would mean we would need a gentler slope to the shore to work in scale. Your scene above I think would struggle with this, the scale in yours looks more like the side of an estuary, which I must say is damned good.
