Step 10

Cut out the branches 2 and place it in the left of the main document. Convert this layer to a Smart Object and change this layer mode to Soft Light 100%. Add a mask to this layer and use a soft black brush , the opacity about 30% to reduce the visibility of the part in the middle.

Step 11

Apply a Gaussian Blur of 18 px to this layer.

Step 12

Make a Curves adjustment layer (set as Clipping Mask) and increase the lightness.

Create a Hue/Saturation adjustment layer and change the Saturation values to -52:

Step 13

Open the branch 3 image and use the Move Tool to drag it into the main document and convert it to a Smart Object. Place it in the top right of the canvas and change its layer mode to Soft Light 100%. Use the Free Transform Tool (Ctrl+T) to rotate it a bit as shown below:

Add a mask to this layer and use a soft black brush to remove the part in the middle, making the branch fade into the background.

Step 14

Apply a Gaussian Blur of 15 px to make it softer and integrated with the background. 

Duplicate this layer and change the mode to Overlay 80%. Right click  this layer, choose Delete Layer Mask and use Ctrl+T to  place it in the bottom right of the canvas. Change the radius of the Gaussian Blur filter to 12 px.

Step 15

Isolate the branch 4 and place it in the top left of the main document. Apply a Gaussian Blur of 15 px to this layer.

Step 16

Create a Hue/Saturation adjustment layer to change the leaves' color:

Step 17

Make a Curves adjustment layer to darken the branch. On this layer mask, paint on the leaves on the front to reveal the lightness there.

Step 18

Isolate the model and  place her in the middle of the canvas.

Step 19

Create a Hue/Saturation adjustment layer and change the Saturation values to -33:

Step 20

Add a Color Balance adjustment layer and alter the Midtones settings. On this layer mask, use a soft black brush with the opacity about 10-15% to reduce the effect on the neck and shoulder. 

Step 21

Make a Curves adjustment layer and increase the lightness. On this layer mask, use a soft black brush to erase  the front of the shoulders and face so they won't become too bright.
