I chose not to deal with the background for this drawing, but I added the shadows under each object. The shadows ground the objects and establish the idea that they are sitting on a solid surface rather than floating in air! I can see some problems with this drawing. The white bowl isn't quite right and the base of it, especially, doesn't seem centered, but I am finished with this drawing. I will know a bit more about what to work on and observe more carefully when I do another.
