Shading

To start off I shaded boxes trying to get them lighter than the one before and blended them so theres no harsh lines. I did the same thing on the next one but I blended them all together so that it looks like its fading. I did the same thing with the third one except with color then made a sketch of the sphere. With the sphere drawing, after drawing outlines, I shaded the corners first since they're the darkest colors and shaded the top portion. Afterwards, I started shading the sphere and the shadow with it then the bottom part. I blended everything together until there were no harsh lines and added more shading where it was needed.
