Step 1
Create a new document sized 1200px * 800px, fill the background with a light grey colour, and some random lighting and grungy texture on it as shown below:
Load the "girl" stock image into Photoshop, cut out the girl from the rest of the image, place her to the lower left side of the canvas:
To bring out some light on the girl image, add the folloing two adjustment layers onto it (make sure to tick the "use previous layer as clipping mask" option when adding them)
Levels
Curves
and here is the effect so far:
Step 2
Now create new layer, and random paint some abstract textures around the girl:
Now apply a layer mask on this abstract painting layer. On the layer mask, use a mixture of grungy, halftone, and hard circle brush, as shown below:
Now let's add some light strips. Create a new layer and grab a soft round brush, do a single click on the top edge of the canvas:
Compress it down as shown below:
Rotate this light strip as shown below:
Duplicate this light strip layer a few times, scatter them around the girl for more effect:
and here is the effect so far:
Step 3
I decided to turn this image into a darker version (just my personal taste), so I went ahead and add the following two adjustment layers on top of all previous layers:
Levels
Add the following layer mask on the Levels adjustment layer: (as you can see, I apply some light grungy texture, plus some hard circle brush on where the girl is)
Curves
Layer Mask on the Curves adjustment layer:
and here is the effect so far:
