To blend this layer properly with the rest of the image change its Blending Mode on Color and lower its Opacity on 20%.
Step 16 - Adding Plasticity
It’s time to add more plasticity to your image. It basically means that you want to make highlights lighter and shadows darker. Add new empty layer on the top of all layers and name it PLASTICITY. Change its Blending Mode from Normal to Soft Light.
Grab the Brush Tool (B), select some soft round brush, pick black color and set the Opacity of the brush on 10%. Paint over the shadows on the picture to make them darker. After you're done switch to white color and paint over the highlights. To get better idea of where you should paint let's take a look at the following picture. You should paint with black over the parts highlighted with red color and with white over the blue parts.
On the following image you can compare how the photo manipulation looks before and after this step.
Step 17 - Creating Interesting Light
To make your photo manipulation more interesting you'll add some light behind the woman in this step.Start by adding new empty layer on the top of all layers and name it LIGHT. Take a look at the following image to see your layer order so far.
Change the Blending mode of the layer LIGHT from Normal to Color Dodge. Grab the Brush Tool (B), select some soft round brush and set its Opacity on about 10%. Pick some orange color ( I used #b68854) and paint around the edges of woman's hair, face and dress. Paint also around the light source behind the woman. Take your time with painting and build the light effect slowly to get the most realistic result.Take a look at the photo below to see where you should paint. Those parts are highlighted with red color.
Step 18 - Retouching
There are still some parts of the image which should be lighter or darker to create more balanced feel. You'll fix it in this step.Add new empty layer on the top of all layers and name it RETOUCH. Change its Blending Mode from Normal to Soft Light. Grab the Brush Tool (B). Use the same setting as in the previous step, only switch to black color. Paint over the areas highlighted on the following image. As you can see you should make the bottom part of the image and the bottom right corner bit darker to draw the attention to woman. Also there are some too bright parts in her hair which should be bit darker.
After you're done pick white color and paint over the highlights in woman's hair. You'll make them healthier looking. See the image below for an example.
