Convert this layer to a Smart Object and use Cmd/Ctrl+T to transform it into a line, place it above one of the model arms, between the white lines:

Change this layer mode to Linear Dodge 100% and duplicate it, place it above the another arm:

Step 37

Duplicate this layer twice and use the Warp Tool to bend it. I placed them at the top left and right:

I applied Gaussian Blur with 3 px to them to soften the edges:

Step 38

Make a group for this light effect and change the group mode to Linear Dodge 100%. I used Color Balance for this effect:

On this layer mask erase the light lines on the model arms:

Step 39

Drag the nebula 4 image onto the white circles, change the mode to Screen 100%. Use the Warp Tool to tweak the effect a little:

Use a layer mask to erase the effect as shown below:

Duplicate this layer and place it onto the model body:

Step 40

Open the wireframe pack. I choose a triangle one and put it inside the white circles:

To invert its color, go to Layer > New Adjustment Layer > Invert:

Step 41

Duplicate the planet 1 and place it inside the wire triangle. Place this layer above the planets group and change the mode to Normal 100%:

I used Curves to reduce the planet contrast:

Step 42

I used Color Balance to change its color:

Step 43

Open the light effect pack. I chose the number 40 and duplicated the background layer. Go to Filter > Liquify and tweak it as done with the nebula 3 in the step 18:

Place it onto the model body and change the mode to Screen 100%. Use the Warp Tool to bend it a little to fit the model body:

Duplicate it five times and arrange them around the model body to make the light effect more visible, use a layer mask if needed to remove the unnecessary parts:

Step 44

Duplicate the first layer twice and make them bigger using Cmd/Ctrl+T. Place them inside the white circles:

Use a layer mask to erase some unwanted details and make the effect more subtle:

Step 45

Make a group for the light layers in the two previous steps and change the group mode to Screen 100%. Use Color Balance to add more warm tone to them:

Step 46

It's time for coloring the scene. Create a Gradient Map adjustment layer on the top:
