Gday guys, i will explain the process of this image briefly.

After chopping up and moving around parts of the image, we are left with the body of the chick upside down making the nest, and the head moved higher above a clone stamped torso. Use pen tool to create the outlines to clonestamp within for the birds body and wing. Have masked feathered areas to indicate the rim of the nest, no need to be too accurate at this rough stage.

Create the second wing using the pen tool and let them fall behind the cage fence (cropped from the original image). Continue to clone stamp away areas of repetition and get to a closer pixel level around areas of focus such as the birds breast and shoulders.
It gets very tricky to mask the edges of what is a very furry bird, rather than attempting to acheive this, have linked back to a hair brush set, begin to use this at a small scale around the body and clone stamp to speed up the process so the edges look natural.

Complete using hair brushes around perimeter of chest area and begin to make the birds talons. The talons are essentially links in the metal fence, copied and altered with the warp tool and then copied and rotated.

The pads of the feet are copied cicular links from the chain and clone stamped to be smoothed out. The wings appear quite flat, before clone stamping the areas, brush tool is used to indicate the undulations in the wingspan.

Use the shading under the wings on a seperate multiply layer and clone stamp feathers underneather on another layer. The baby chick is a flipped horizontal and rotated version of the same birds head fromt the source image, copy and invert the beak to make it appear open. The eye is tricky and begins with the pen tool to make the general shape and the pupil.

Fill the pen area for the eye with the gradient tool and fill black the pupil, clone that layer and make slightly larger for the outer pupil, dodge and burn the eye some more to make a more distinct shape and brush some white in the top corner for some slight reflection.

Copy the stone from the source image and flip it horizontally as a base for the bird figure. Use colour contrast to encrease the amount of yellow in the juvenile birds feathers.

Clone the baby chick and rotate, clone stamp some areas and you have the second asleep baby. To make the tail create a path with the pen tool. Save the path as it will be used multiple times. Brush the path with a level of decay set in the brush setting so it gets thinner the further it gets from the anchor point. Brush the path repeatedly changing the brize size to 20 pixels less each time and with a slightly darker colour, when done apply guassian blur to smoothe.

For the final step go to edit and define a basic pattern with the feathers. Use the same path and use pattern stamp to project this pattern to the tail already made and apply as a screen layer. Dodge and burn it to make it more 3D. For the end of the tail, copy a piece of the feathers over and use smudge to push out the plumes fromt the center, duplicate it and adjust darkness repeatedly to give it several layers, merge them and then warp to get the appropriate shape. Use smudge to smooth out the undersides of the wings as well.

From here it is just a matter of dodging and burning shadows and highlights for the final image.

Just a quick description for the updated talons, use marquee elipses to shape the claw and dodge and burn to make it appear more 3D. Use brush along a pen tool path to make the basic extended talon shape and go to town with liquify & dodge/burn to make variations in the shape and make appear more 3D.

Clone the first talon and rotate to make the others, warp them to make variable shapes. To make the spotty texture just use a dry brush on a seperate layer and feather off towards the edges. Brush in the webbing inbetween the talons and dodge and burn everything.

Clone stamp parts of the talons to make the basic shape of the foot pad and copy another talon flipped horizontally to make the bottom claw. From this point merge the talons and copy/warp them to make the second foot. Dodge and burn everything until the talons fit with the background image.
