I cant give a complete guide, there's just to much steps. The technic I developed is using only the smudge and brush(a lot of dodge and multiply) tools.
BUt here we go: Duplicate layer and resize using transform tool.
step 2 of 7
Create a little bit of a surrounding using the brush tool, just use your imagination.
step 3 of 7
Smudge eveything you have brushed so far. With the smudge tool you can easily create nice clouds.
step 4 of 7
This is a big step, I used the brush tool to create the mountains. I also duplicated the layer flipped it vertically and stamped part of that layer to create the mirror effect.
step 5 of 7
This is what I mean by smudging, you can create really realistic images with that tool. I also used the color brush to give the foreground a sandy color.
step 6 of 7
I changed the color again. This time using image- adjustments- color balance.
I also created the clouds using only a brush and the smudge tool.
step 7 of 7
I finished the image with the trees, the house and some more clouds. By Doing that I felt the image became more alive.
