Actually "something" is already lurking there, in full daylight. But sort of half camouflaged. But I think Andromeda may have seen it down there.She's got a nice day for it, anyway.
A good image with some nice foreshadowing, I think. Sure it's pleasant now, but what happens when the sun starts to go down? Somewhere, lurking in the deeper water is something. Excellent work with the composite figure, and the current resolution is consistent with the background photo, so it all looks seamless.
