Here's a landscape by Frank LaLumia that demonstrates working into a wet area with increasingly thick paint. That purple wash was applied good and wet, and LaLumia brought the other colors in while the initial wash was not yet dry.
Trevor Chamberlain makes a gorgeous shadow behind the figure on horseback by starting with an overall wash and bringing in variations on the color while the area was still wet.
If you brought home one of the photos that were selected for their passages that would welcome a wet on wet treatment, pick out those areas and give this approach a try. Feel free to fill the page with various attempts. It's not necessary to paint a proper finished painting.
