Now go to Edit > Fill ... or press Ctrl + F5 on your keyboard to activate the Fill dialogue window. As Use select the option Color.. and pick pure black color.
Press OK. The mask is filled with black and the adjustment is visible only on dinosaur's head.
Press Ctrl + D on your keyboard to deselect the mask.
Step 15 - Whiter Teeth
To bring bit more contrast to the upper right side of the image you'll make dinosaur's teeth slightly lighter in this step.
Add new adjustment layer Levels on the top of all layers and set the Input Levels on 0; 1,55; 255.
Grab the Paint Bucket Tool (G), pick black color and fill the layer mask with it. Now grab the Brush Tool (B), set the Master Diameter on 10 pixels, the Opacity on 50% and pick white color. Paint over the teeth.
If you're not sure you can take a look at the following picture where to paint. That areas are highlighted with red color.
Step 16 - More Diffused Light
The picture would have stronger, more magical atmosphere if there is more light coming from the left through the trees and mist. You'll add it in this step.
Add new layer on the top of all layers and name it DIFFUSED LIGHT. Grab the Brush Tool (B), set the Master Diameter on about 500 pixels and set the Opacity on 5% - 10%. Pick some very light color and paint a strip coming from the upper left corner to woman's head.
On the following photos you can see the stripe with black background (don't make that black background!) and with the real background of the photo manipulation.
Step 17 - Toning of Woman's Face
As I mentioned in one of the first steps woman's face is very bright, right now she looks more like a vampire than a human. So in this step you'll add some colors on the skin.
Add new layer on the top of all layers and name it e.g. SKIN TONING. Grab the Brush Tool (B), set the Master Diameter on 30 pixels and the Opacity on 20%. Pick light orange/brown color (e.g. #e0c7aa) and gently paint over the woman's forehead, left cheek and right hand.
Let's take a look at the following images. The first one shows woman's face without any retouching. On the second you can see what and where to paint, there is black background put under so you can see it better. On the third image there is woman's face after this step.
Step 18 - Adding Depth
In this step you'll create depth by adding vignette to your picture and by darkening woman's hair even bit more and part of dinosaur's head.
Add new adjustment layer Levels on the top of all layers and set the Input Levels on 0; 0,7; 255.
You want to adjust only part of the image. Grab the Paint Bucket Tool (G), pick black color and fill the layer mask of the adjustment layer with it. Then grab the Brush Tool (B), set the Master Diameter on about 250 pixels, lower its Opacity on 30% and paint gentle vignette around the corners of the image.
After that make the Master Diameter smaller (60 pixels) and paint over woman's hair and left part of dinosaur's head.
Let's take a look at the following photo where is highlighted with red color where you should paint.
On the picture below you can see how your photo manipulation should look like so far.
