I first got three images that I would want to put together in a collage. The first thing I had to do was set one of them as a background. The other two I had to use the lasso tool and wand tool to get the figures I want.
While trying to manipulate the images, I found it was difficult to get smooth edges. Thus, the figures in the collage are noticeably grainy.
