Then paint out this layer: Layer ? Duplicate Layer (ctrl+j) and select Edit ? Free Transform (ctrl+t) option to turn it around and change the size of this set of circles:



Combine the background's and the sky's layers (ctrl+e) and apply to the new layer a special filter: Filter ? Render ? Lens Flare, setting the flare in a way to be situated under the circles.





Next we'll create a brush of our own, having the star's shape. For the beginning we have to open a new file (400x400 px). Draw a star on it, selecting the Custom Shape Tool of black color:



Apply the next command: Edit ? Define Brush Preset and change the adjustments of the brush in the Brushes window.



Then create a new layer, under the land's layer. Change its Blending Mode on Overlay and insert the stars on it.



On the layer above, we have to create several rays painted in white color (Paint Bucket Tool).
