Look how your image should look after this step:

Step 14 - Adding "3D Effect" To The Legs

As you can see the texture on woman´s legs is flat which doesn´t look realistic. We will fix it now.

Add new layer on the top of your layer. Grab the Gradient Tool (G) and fill the layer with solid #808080 grey color. Change the blending mode of the layer on Overlay.

Grab the Burn Tool (O) and start burning the areas of her legs which should be darker. Then grab the Dodge Tool and lighten areas which should be lighter as it is shown bellow:

As you can see I also darkered the area in front of the woman. It seems bit light to me.

Step 15 - Adding the Ravens

Download the picture of ravens. This stock is really great because it´s on transparent background so you don´t have to cut out the background which saves a lot of time.

Open the picture with ravens and grab the Marquee Tool (M), select raven you want to use and drag it into your manipulation. Do the same with all ravens and place them as you can see on the preview picture or whatever you like.

Step 16 - Adding Small Feathers

To add feathers you need to download these brushes and install it into Photoshop. To get variety which will look realistic you need to set dynamic of the brush. In Photoshop CS3 you can find the button Brushes left to the Navigator.

First set the Shape Dynamics as it´s shown bellow:

Size Jitter sets how much can be size of the brush different from the size you set. Angle Jitter causes that the feathers will have different angels and the Roudness Jitter adds bit roundness which increases the variety little more.

Now set Scattering as it´s shown bellow:

Create new layer on the top of your layers and name it SMALL FEATHERS. Pick dark grey or black color and paint some feathers.

After this step your manipulation should be similar to this one:

Step 17 - Changing the Light on the Ground

In this step I will show you little trick how to easily change the lights and shadows on the ground so they will fit to the lights of the sky. As you can see there are some lighter and darker parts on the sky and they should reflect on the ground too.

Right click on the layer SKY and select Duplicate Layer. Name this new layer LIGHTS ON THE GROUND and place it on the top of your layers. Now go to Edit > Transform > Flip Vertical. Grab the Move Tool (V) and place the layer over the part of the manipulation where the ground is. Press Ctrl + Shift + U to desaturate the layer.
