Add a layer mask to the boat layer. Mask away the bottom of the boat so that it looks submerged in the water.
Create a clipped Hue/Saturation Adjustment layer. Drag the saturation slider to -66.
Create a clipped Curves Adjustment layer. Drag the curve down to darken. In the layer mask use a soft white brush at 50% opacity and 2-3px size to create some lines along the lines of the boat.
Create a new layer and clip it to the boat layer. Sample a blue color from the water and with a soft brush at 2-3 px create some blue lines along the boat. This step is just to have some color variation in the boat.
Create new layer and clip it to the boat. With the chalk brush draw some blood spots on the boat surface.
Create a new layer. With the chalk brush at 40-50% Opacity draw some small waves splashing into the boat.
Open the file “Fisherman”. Make a selection of the fisherman (with the pen tool). Copy and paste the fisherman into our working document. Convert it to a smart object. If needed create a layer mask to hide additional parts of the fisherman.
Create a clipped Curves adjustment layer. Drag the curve down to darken the fisherman until he is just a silhouette.
Create a new layer and clip it to the fisherman. Sample a light blue color from the sky or sea and paint some light on the left side of the fisherman as shown below. No need for great precision, just the general feeling of light hitting the left side of the fisherman.
You may notice that the fishing line is not complete. Create a new layer and with a black chalk brush at 1px size complete the line to the sharkï¿½s mouth.
The fisherman while fighting the beast should have some blood on himself. Create a new layer and with the chalk brush draw a couple of red spots on the fisherman. Group all the layers related to the fisherman and name the group “Fisherman”.
Time to add some splashes. Open the file “Splash1”. Choose Select > Color Range. Click once on a white spot on the image to make a selection of the drops and click ok.
Now that we have a selection of the splash press Ctrl + J to make a new layer from the selection. Ctrl + A to select all, Ctrl + C to copy and while back in our working document Ctrl + V to paste the water drops.
Add a layer mask and mask all the unwanted parts until you have something like the image below.
Repeat the steps 59-60 two more times to add splashes in the indicated regions but this time using “Splash2” image.
Import the splash brush. Create as many layers as you see fit and create splashes on them using the brush. You can mask portions of the splash you donï¿½t like. Place some splashes around the shark and some around the boat. Group all the splashes together and further add a layer mask to the group to refine where the splashes are.
Create a Color Balance adjustment layer. Use the settings shown below in order to achieve a darker, more interesting mood.
Create a new layer and set the blending mode to Overlay. With a soft brush paint with white over the areas indicated below in order to emphasize them.
