Step 10

Create a Curves adjustment layer to darken the background a bit. On this layer, use a soft black brush to erase the area around the model's face to create the light source.

Step 11

Move the light 1 image onto  the canvas and change this layer's mode to Screen 100%. Add a mask to this layer and use a soft black brush to remove the hard edges and the part covering the model to blend the light with the background. 

Step 12

Apply a Gaussian Blur of 15 px to this layer.:

Step 13

Make a Levels adjustment layer to increase the contrast and shadow of the effect. On this layer mask, use a soft black brush with the opacity about 30-40% to reduce the dark effect on the edges as the screenshot below shows:

Step 14

Create a Color Balance adjustment layer and alter the Midtones values:

Step 15

Add the light 2 image to our main document and change the layer mode to Screen 100%.  Add a mask to this layer to remove the part on the  foreground and on the model, also blend the light with the existing background:

Step 16

Apply a Gaussian Blur of 4 px to this layer:

Step 17

Open the sci-fi background  1 image and add it to the top left of the main canvas. Change this layer mode to Screen 100% and duplicate this layer and move it to the model's head. Use the Free Transform Tool (Ctrl+T) to rotate it to fit the pose of her head.

Step 18

Add a mask to each of these layers and use a soft black brush with the lowered opacity (about 30-40%) to blur some details of the effect:

Step 19

Select these layers and hit Ctrl+G to make a group for them. Change this layer mode to Screen 100% and create a Color Balance adjustment layer within the group.

Step 20

Use a Levels adjustment layer to remove the hard edges completely, also increase the contrast of the effect. 

Step 21

Make a new layer on top of the layer and use a small hard brush with the color #afccff to paint the light's reflection on the hair and the head of the model.

Step 22

Open the light 3 images pack and choose  the image 2. Place it onto the area of the sci-fi background 1 and change the layer's mode to Screen 100%.  Duplicate this layer three times and resize them down and arrange them in the lower section of  the sci-fi background 1. Use Ctrl+T to rotate them as shown below:
