Well The reason why I did those the three pictures were that I love my grandma so I chose her. I also made sure that her background was interesting but I also made it s that the background isn't totally distracting. The reason why I chose to to the mountain was because It was a beautiful day and The beautiful sleeping giant was in my back yard. But before I had thought of that I was planning to hike up the mountain. so for the third image we had to combine the the first two images. I did all of this in photoshop it was really amazing.
