Work in progress: how to bring light values back into a painting

What do you do when a painting has become too dark or has opaque passages where you really would like shining translucent color? 

Overpainting in white can help. Here are images of the painting after opaque whites were added back into the composition through:  drybrushing white paint and some gesso and knife painting additional textural areas with light molding paste.

Notice how the added molding paste brings variety to the mark making and unified some larger shapes.

Now, glazes are able to shine when they are added over those whitened areas. Images of the glazing are coming soon.
