To do an exercise similar to this one, you can download a picture of a sky, an arm, and several sketches of birds (with a white background). First, select the arm using the Magnetic Lasso Tool and move it to the sky picture; you can rotate it, shrink it or enlarge it if you wish. Second, add images of birds, or sketches of birds; an easy way to do this is to select the whole image (Command-A), drag it into the Sky image, rotate it and enlarge it or shrink it, and then select the option "Linear Burn" in the Layer's Panel options window - the white background disappears this way (ask Mrs. Feld if you cannot find it).
Note: to easily rotate images horizontally or vertically you can go to Edit - Transform - Flip Horizontal or Flip Vertical.
It's an easy and fun exercise to do. You can use this technique with other ideas, but I need to see that you used and understand this technique. Create a "similar" exercise and download it in Edmodo.
