I prepared oil washes, by first letting excess oil soak into a piece of cardboard.
The lantern trees have the color progression from purple over green to the tan; so they got a purple/green oil wash into the lower areas, that was then blended into a brown wash for the upper part.
The garlic shrooms don't have the green, so here I used purple/black blending into brown.
After letting the oil washed cure for ~2 hours, I removed the wash from the raised areas with make-up sponges.
The oils have now to dry thoroughly, before I will follow up with a final drybrush.
