In the next step of my project, I’ve worked out where to place the mushroom, taking into rule of thirds into consideration and also the placement of the leaves on the grass.
Next, I’ve duplicated the background image of the grass twice, moved them into the foreground and added layer masking to them to blend the bottom of the house and the bottom of the steps into the grass. I’ve added shadows to the grass around where the house sits and blurred the background so that the subject is more in focus.
