Stages of Painting "River Power"

Sometimes I photograph different stages of a painting I'm working on - it's kind of interesting to look back at the images to see where various areas of the painting came to life.
The colors in the 3rd and 4th images are not accurate on the right hand side of the painting; the lamp at my painting table reflected on the still wet paper and made the images look a lot more golden brown than the painting really is. Final result is the image at the bottom; the colors in the image more accurately match the actual painting.
