These are my initial selections that I have used to create my image.
step 2 of 16
I have combined the little foot with the toes in order to create the mushroom hat.
step 3 of 16
Have aded the body of the mushroom from foot.
The gates are made from the foot as well, resized to have a very slim shape.
The horn is made out the foot as well.
step 4 of 16
Added the door and windows, created from entire foot (with toes), flipped horizontal and masked into each other.
Added the spots on the mushroom from initial toes.
step 5 of 16
Colored mushroom hat using hue/saturation.
Using a layer mask, I have revealed the curtains from initial mushroom image that I have also used as a reference.
I made the mushroom and the first portion of the grass smaller.
And then from the same portion of grass, started to create little grass hills by rotating, resizing and flipping horizontal.
Finished with the hills.
Added some other kind of grass in between the hills layers. It was very useful that I found this PNG transparent file on obsidian dawn. As a tip ....PNG files are very very useful as we don't have to mask them anymore. What I had to do though was to defringe them along the way (under layer/matting)
Here I added two types of backrounds. I set the blending mode of the orange layer to overlay, to reveal some colors, but also kind of blend them into each other.
Here I added a funny sun.
You won't find this in the final result anymore as a lot of people commented that it didn't fit the image theme...so I decided to delete the glasses and the mouth and kept only the shape of the sun..
Here I have flipped the mushroom horizontal for composition purposes (to fill in the blank right side of the image).
Have created the little grass islands from the first initial grass selection, gave them some perspective and masked them to blend into the water.
Added some glow to the sun using outside glow, blending mode screen, then added some light beams underneath and a light yellow gradient map over the bottom part for highlights.
This is the final result after I erased the suns glasses and mouth.
As I flattened the image meanwhile and I didn't want to go through the whole lighting process...I used the clone tool and the healing brush tool to cover the glasses and the mouth with other clear yellow portions from the sun.
