Added fishing pole from another source also small air bubble coming from it. Added text to pole handle. Applied Linear Light blend to pole to blend it better with water. Also applied a slight blur to it.
Applied a color fill layer with average color of the water. Used Color blend mode, reduced opacity to 17%. This will help color match the items in the water.
Then added blood in the water. Soft reddish brush. Blend Linear Light. Adjusted opacity down.
Finally applied Camera Raw to the entire scene.
I like the Artistic 7 color preference for this. I lowered the amount slider to 55% as it was looking a little too green.
