Open the Mountain 1 background stock and copy it (C) and paste it (P) over the skies backgrounds.
Apply a Free Transform tool (Cmd/Ctrl+T), flip horizontally and transform it into the scene. Then apply a layer mask to it and using a low opacity brush of around 30-40%, mask the sky part as shown in the section below:
Add a levels adjustment layer in clipping mask. Go to Layer > New Adjustment Layer > Levels and apply the following values:
Now open the second mountain stock and copy (C) it over the main document as a top most layer. Apply a free transform tool (Cmd/Ctrl+T) and scale it to fit into the main scene.
Add a layer mask to it and mask the area using a soft brush (B) with a low opacity brush of around 40-45% as shown in the selection below:
Create a Levels adjustment layer using a clipping mask to brighten and change the colour of the mountain background. Apply the following values shown below:
Then create a curves adjustment layer again in clipping mask to further enhance and brighten the scene.
After that apply a Hue/Saturation adjustment layer to desaturate the mountains slightly and blend in with the whole scene:
Now open Landscape stock, we will make that as our ground. Activate the free transform tool (Cmd/Ctrl+T) and enlarge it to fit it into the whole scene. Then give it a layer mask and mask away the part using a soft, low opacity brush (35-45%) as shown in the section below:
In clipping mask, create a Brightness/Contrast adjustment layer and set the brightness to +7 and contrast to +8 to brighten the ground and add a bit of contrast.
Then create a Vibrance adjustment layer, in clipping mask and set the vibrance to -22 to decrease it's vibrancy and make it a bit desaturated.
We will add a bit of shadow and lighting by applying Curves adjustment layers. Create the first Curves adjustment to darken the ground. Fill this layer mask with black by hitting Cmd/Ctrl+Backspace on the keyboard. Then using a soft brush 100% opacity, and with your foreground colour set to white and background colour to black as shown in the image below, reveal back the effects of the curves layer:
