I believe the tide was classified as low at the juncture in time this image was taken.
The colour of the water contrasts quite a bit against the colour of the rocks and rock oysters, I think.
A few different textures and some nice variation in detail, and so on.
I hope you enjoy.

About Stupidity Hole
I'm some guy that does stuff.
Hoping to one day fill the internet with enough insane ramblings to impress a cannibal rat ship.
I do more than I probably should.
I have a page called MS Paint Masterpieces that you may be interested in checking out.
I also co-run Culture Eater, an online zine for covering the arts among other things.
