If you've done your mask correctly, you will have arrived at something like this.

Create a new Layer (Layer > New > Layer). Select the bottom of the document. A good way to do this is quickly and accurately is to select the "mountain copy" layer because you know that it is half of the screen. To do this, go into your layers palette, select the layer "mountain copy" (control/command + click on the icon for the layer "mountain copy").
Note: If you cannot seem to select the layer by clicking on it, you are probably clicking the wrong thing. To the left of the layer name, there is a small icon of the layer. You should control/command + click on that image, not the text itself.
Select a blue for your foreground (I choose #216a82) and black for your background, and create a gradient. Set the opacity for this layer to 50%.

Create another new layer (Layer > New > Layer), and call it "lens flare". Fill this layer with black using the fill tool (G), and then head up to Filters > Render > Lens Flare. Select 105mm Prime, and leave the brightness at 100%. Then center the lens flare as best you can (if you miss the center you can always undo and try again, or just move it using the move (V) tool)0.

Using these settings you should get this:

Go to Image > Adjustments > Brightness/Contrast and move the contrast to the highest level possible.

Go to Image > Adjustments > Hue/Saturation and move the mimic the settings below.

Just look at your layers palette and make sure that your layers are like this (order and number of layers should be the same as this). Then, set the blending mode for the layer "lens flare" to linear dodge (add).
