I used magnetic lasso tool to cut out the pig from this image. I used a mask to hide the grass, and I used the clone tool to copy one of the back feet to the front.
step 2 of 4
I used the magnetic lasso tool to cut out the sofa. I also made a quick mask to refine the selection. When the selction was ok, I gave it a 1 px feather, inverted it and removed the rest of the image.
This is the third and last image I used. I flipped it horisontal to make the light come from the left (because the sofa image had light from the left), and I rotated it to make the ground horisontal - best for pig sleep.
step 4 of 4
In the last step I simply copied the pig and the sofa on to the landscape. I transformed the size and rotated them both to make them fit. I had to remove some grass from the pig using an soft brush and a layer mask, and also clone one of the back legs.
