I tried it again. I simplified, took away the bowl and the can of corn, and had a little fun with the label on the bottle of hot sauce. I'm happier with this result.
Notes about watercolor: It's so easy to go too far. It's so easy not to go quite far enough.
On the first one, I went too far on the avocado and it got muddy, so I was careful to leave variation in color on this one. On this one, I was about to call it a day when I noticed the tiny cast shadows beneath the stems of the tomato, onto the tomato's surface, so I added those and it really improved it.
As I look at this one, I can see that I need to go back in with a little more shadow on the underside of the garlic bulbs, as I did on the first one--I'm still a little hazy on the effects of cast shadow (especially when the objects are in weak, neutral light rather than with a strong light source, as these were on my patio). Practice, practice, it all gets used. On to the next recipe...
Question: Does it bother anybody that there is no horizon line? Do the cast shadows sufficiently "seat" the objects on a surface, without indicating a surface in some other way?
