Open the Underwater stock, drag it onto the main scene, and place it on top of the bottle within the underwater group.

Go to Edit > Transform > Distort and arrange it according to the perspective of the bottle. While distorting, hold the Cmd /Ctrl key on your keyboard and press a point on the corner to distort it freely and smoothly.

Then using the layer mask, remove the hard edges with a soft brush:

Step 77

Take the underwater stock again and place it on the left side of the bottle. Distort the water as we did in the previous step and then using a layer mask, remove the hard edges with a soft brush.

Step 78

Select both the underwater layers, duplicate it and then merge (Cmd/Ctrl+E) them together.

I took only the bottom part of the underwater, so use a layer mask to delete the upper part.

Set this layer to Multiply – 29%, to make the water a bit darker.

Step 79

First desaturate the water by applying a Hue/Saturation layer.

Hue: -16, Saturation: -48

Then create a Brightness/Contrast layer to reduce the brightness of the bottom section of the water. On its layer mask, brush away the effect from the middle section.

Brightness: -66, Contrast: +41

Next, apply a Photo Filter adjustment:

Step 80

Lastly, create a Curves adjustment to darken the water scene:

Step 81

I wanted to add a bit of magical touch inside the bottle scene.

Open the starry fractal stock, resize it accordingly with the transform tool and place it on the sky part. Then change it into Screen blend mode.

Now load the starlight brushes and select the brush shown in the preset. With a white colour, opacity – 100%, paint some over the sky as well as on the underwater scene.

Step 82

Take the moon stock, go to Edit > Transform > Flip Horizontal and place it on the water scene.

Now duplicate the moon layer and using a layer mask, erase the bottom half of it like this:

Do the same for the other copy of the moon, but this time erase the upper half of it using a layer mask:

Step 83

First, duplicate the underwater layers and also the Hue/Saturation layer applied to it and bring it on top of the bottom moon layer. Then merge (Cmd/Ctrl+E) all the three layers (two underwater layers and the Hue/Saturation adjustment) and set it on clipping mask:
