Value Studies of Central Park

These value studies show white->black, then done in a warm color and a cool color. I have a really hard time establishing values especially in color. There is just such a small variation and the color washes often dry lighter than I think I am seeing them initially when wet. A frustrating but necessary exercise. This is the hard part of art, trying to learn the science behind what makes a painting work or not - values, composition, highlights, low-lights, so much to think about!
