using the original source i created the body of the larger snake.

i cut out part of the tree, duplicated it, flipped, masked out the edges in order to have a smooth transition between the parts. duplicated again and again, cloned out some parts to avoid obvious repetitions, then using warp and liquify i made the body of the snake.

using the leaves contest source i created the "hair" of the snake.

i cut out the leaf, warped, duplicated warped duplicated warped duplicated and so on, i used many warped versions in order do avoid repetitions, at some point i probably had somewhere about one million layers (or maybe just a little less)

then merged some of them together, duplicated warped, masked...

finally i got what you see below.

using the stone ball contest source i made the egg, first cutting out the ball,then spherizing and warping.
then using pen tool i selected two parts of the egg i wanted too keep, put them one over another and i got the egg.

using the sowing wheel contest source i made the small snake, using practically the same steps as for the body of the large snake.

finally i put the small snake inside the egg ant the large snake surrounding the egg.

from stones source image i cut out several stones, waped them to fit my needs, then arranged them around the snakes, putting some in the background as well.

using grass source i added the grass, using burn i made the shadows under the rocks and snake. i blurred the upper part of the ground in order to give an impression of depth, also blurred the large rocks from behind the snakes.

using the pen tool i made a bird-like shape, multiplied it to make the birds flying around one of the mountains from the background.

finally added the sky and masked out some parts of the rocks from the background to make the impression that the top of them are in the clouds.
