Hi Danny,
That has a really nice feel to it.
If I could offer any advice. I'd be tempted to use a wider aspect ratio for a shot like this, which could also give you more depth, by brining in the horizon to the left of frame.
I'd also add an extra element to the foreground, perhaps a small rowing boat, that would cover the immediate false looking waves on the shore. I've tried a few times to achieve these and those kind of shallow shorelines are difficult to create, yours however, look very natural for the most part, and the subtle foam is very nice.
Some, even maybe subtle texture on the distant islands would help, as they stand in stark contrast to the lush foreground.
Also watch out for that uniform line that runs up the beach, probably from your shoreline mask/displacement, you might want to break it up a little.
Hope that's not all too much crit.
Chris
