I like this. Kinda creative. I like too the that water is green. I can't decide if it helps or hurts that the center of you photo isn't what is seen first. A little backwards focus never hurt anyone right?
Interesting image. My eye is drawn to the brighter reflection on the right side of the image rather than the "orb" though. Perhaps a shallowed depth of focus may have helped bring the central object more to the "forefront" of the image.
Fishing bobber? I like the post processing. I think this could really stand out if the bobber had a bright red stripe on it as most I've seen do (of course then you probably wouldn't be keeping true to the scene), but the bright color against the dark and weathered background would add to the story here imho.
