I duplicated the starry-1 layer to add more stars on the left side of the sky.
Add the Shooting Star
For the shooting star I used the lens flare pack. Open up the lens flare pack and choose optical_26 lens flare image and add it to main document. Rotate it using Transform Tool and change its blending mode to Screen.
Using Hue/Saturation adjustment layer I changed the color of the star. You can see the settings below :
Hit CTRL + SHIFT + N to create a new layer and set the foreground color to #161231. Use a soft round brush to paint lights on the sky to brighten it as it looks too dark.
Set the blending mode to Screen and lower the opacity to 46%
Get back to lake layer and lower the brightness using Curves adjustment layer.
Create the Light Effects
Create a new layer and set the foreground color to #9a5824. Using a soft round brush paint the light as shown below.
Change the blending mode to Linear Dodge 100%.
Make a Gradient Map adjustment layer on top of all layers. Choose the gradient color flow from #091d2c to #5e451a.
Set the blending mode to Color Dodge 100%.
I use a Curves adjustment layer to add more green color tones to scene using Green Channel.
I used another Curves adjustment layer to lower the brightness of whole scene.
On the layer mask of this Curves, I masked the effect on the red highlighted area using soft round black brush and keep the dark effect on the rest of the parts.
Results so far :
Create a new layer and use the color #4b2c0f and paint the light reflection on the trees and wherever you think that this parts is going to illuminated by the lights. Always use soft round brush for painting lights.
Change the blending mode to Color Dodge and lower the opacity to 36%.
Use the Vibrance adjustment layer to reduce the vibrance.
On the layer mask of this, I masked the effect on the highlighted area using soft-medium black brush.
Using Selective Color adjustment layer I reduced the yellow colors from the scene as I wanted different colors. Using Color Balance adjustment layer I introduced new colors to scene. You can see the settings below.
Finally, I adjusted the contrast of whole scene using Levels adjustment layer. Using Selective Color adjustment layer I added dark blue tones.
Final Results :
