UNIT A- In this image I used the crop and marquee tool to crop out the rest of the image then I dragged and rotated the image so the lady appeared to have a different posture.

UNIT C- In this image I duplicated the moons and changed their sizes with the move tool and using the set rotation text box on the options bar.
UNIT D- In this image I used the levels adjustment layer to adjust the colors slider and the history panel to see the changes from the original image to the edited one.
