After I completed the week 12 painting for Jed Dorsey’s Mini Painting Challenge at Acrylic University, and compared it to a grayscale of the reference image, I realized the values were off. So I’ve lightened the trees and the grass.

Here’s the value comparison between the reference image and the original painting, and then the reference and this updated version. The updated pic is, obviously, on the left. My trees and my grass were much too dark in my first attempt.
