I get a good sense of shape from your cup/saucer -- well done! Use a larger brush when painting so that you don't wind up with so many erroneous brush strokes. (Start with a large brush for blocking in your shape, only go smaller for details as you refine.)
Don't paint highlights with white -- it will dull your colors. (White and black don't actually exist in the real world, they either absorb colors around them or reflect them, so when you paint with white on top of colors, it looks very lifeless.) Try to think about what color your light source is and then mix that color (in a lighter value) with the local color of the object you're painting to get your highlight and/or shadow colors.
Keep up the studies!
Don't forget to reflect environment colors back up into the object you're painting -- that green background should be affecting the blorb, especially around the bottom areas.
Here's a fun thing to play with. It's about 3/4 of the way down the page.. (The interactive circle and sliders to adjust color/light.) Play with the sliders and watch how the sphere is effected. Notice the bounce light on the bottom of the sphere and how it adjusts as the environment changes. Knowing how stuff like this works will make your object integrate much more comfortably into the environment you're trying to place it.
