Good to see you work on the fundamentals! If at all possible, try doing studies like your color ball from reference (preferably life), so you can observe what happens before applying it to work from memory. If you don't have a color ball, use some fruit instead - set up a simple light source and paint that. For your color ball, the shadow side is too desaturated - if the ball is colorful, it will still be that way in the shadows. Unless it's the light source that's colored - but then the highlight wouldn't be this white.
But you'll see what I mean if you take a ball or apple and observe it :)

Good luck!
