Let’s start! Create new file 1920×1080 size.

Then, paste Sky levels stock as new layer. You should transform it, to fill canvas. Change blending mode to Multiply.
On this layer, use mask. Try to mask all the trees from the bottom side. you should use big, soft brush (ex. 300px or more). My masking results are below
Paste Stars stock, as new layer. Then add mask to this layer. Again use soft, big brush on contours of mountains.
Change blending mode of stars to Screen.
It’s time to paste moon stock on new layer. Place it as shown. Change blending mode to Screen
