Creating an illustration like this requires many of the principles we learned in this lesson.

The image you created for this lesson may seem simple, but along the way, you learned many vital tools and principles for raster image editing, including what pixels are, how resolution works, how to create solid shapes, how to build shadows from scratch, and how make custom gradients. These basic techniques will come in handy again and again as you refine your skills and make new works of art.

Let's turn in the 3D sphere we made today. Send the JPEG of your final version to your teacher. You work will be graded using the following rubric.

	Criteria
Resolution and File Format 1 point	1 Point: Your image is 640 pixels wide and 480 pixels tall. You saved your final image as a JPEG with maximum quality settings.
Highlights and Shadows 1 point	1 Point: You create a convincing 3D sphere effect using highlights, shadows, and gradients. Your image uses light sources effectively.
Editing Skills 1 point	1 Point: You show a full understanding of the editing techniques from the lesson, including making selections, using layers, and transforming objects.
