Love the watercolor effect on that scene, just suits it perfectly. Its weird, I've got a number of plug-in's over the years that can do watercolor and other effects, such as Toon-It and Sketch, and they have a ton of control and options to them, but somehow Sony's watercolor effect, with little if any control over its processing just always seems to crank out a "perfect" effect, at least in regards to my own mind's eye version of what I think a watercolor effect should look like.
It somehow maintains detail in all the right places yet doing so with a painterly quality, such as on the waves.
Really a fun effect and as I'm sure most know but thats worth repeating for those who might not, you can process an image with the watercolor effect in camera after taking a shot and save it as copy of the original file.
