Autumn leaf colors Picture

Add on a new layer, between the girls' layer and the cat's one, a hat.



Delete its background, applying Polygonal Lasso Tool. Correct the size and the perspective level applying Edit – Free Transform (ctrl+t) and Edit – Transform – Distort. It's necessary for this to hide the visibility of the cat's layer, clicking on the place, picturing an eye, close to the layer.



Correct the hat's color too, using Image – Adjustments – Curves (ctrl+m) and Image – Adjustments – Selective Colors.



Show again the cat's layer visibility and make a copy of it (Layer – Duplicate Layer). Make the copy of black color, making use of the next selection: Image – Adjustments – Brightness/Contrast.



Blur it out, using Filter – Blur – Gaussian Blur.



Move this layer lower than the basic layer with the cat, by applying the Move Tool, placing it downwards. Minimize the Opacity till 34%. It's possible to get this way the shadow.



Apply the same actions to the hat, but here it's not necessary to minimize the layer's Opacity. After that you should change the shadow's color on orange (Selective Colors).



Combine now the layers containing the cat, the hat, their shadows and the girl's one by connecting them together. When you'll get to the top layer, apply Layer – Merge Down (ctrl+e).



Correct a little more the background's layer (Curves)



Copy now the girl's layer and blur it out a little with Gaussian Blur 30. Group out these two layers: Layer – Create Clipping Mask (ctrl+g) and change the blurred layer's type on Linear Burn. Merge down now these layers and correct the color of the new layer, applying Curves again.
