Here I've blocked in the local color on the peaches and have been tweaking color and edges on the grapes. I've also been subtly modifying the shadows, softening edges and working in reflected color. Even though the objects appear fairly complete, there is still a good deal of development yet to come, and I consider them just "blocked in" at this point. I'll be adding detail and color notes all over the place from here on out.
One reason I like to block in the objects in sequence like this (rather than all at once) is that it makes it simpler to work with a selection of brushes and hues that are all in the same color family. I can spread out the palette a bit and mix twelve different shades of oranges and reds, if I want.
The leaves are next, which will be the most complex passage... lots of overlapping shapes and shadows.
