Yellow Colored Lenses

The painting above was painted yesterday . I did it to see how much my style has evolved since I first painted this subject three years ago .

What I notice is that the painting from yesterday has a darker value range. I also see the use of neutrals which help make the colors pop. I think overall the marbles appear rounder in yesterdays painting because I could anchor the round shapes in their shadows better with color mixing and more confidence in my ability to achieve forms.
What I have learned so far:
Sometimes you don't see your own growth until you find  a way to measure it in a concrete way. Doing this experiment allowed me to see how much daily painting has improved my skill level.
And I just have to add.... I no longer rely on cadmium yellow  to achieve brightness.  I have learned to use it sparingly. The bottom picture almost looks like it is being viewed through yellow colored lenses.
