Ron, Robert, stapeliad, and Shallbe, thank you for your comments and your kind words!
Ron, Iím glad you liked the post and the blog!
Robert, yes, thatís what guides me too - warmer colors for the light areas and cooler for shadows, thatís the general idea, but I also use some warmer colors in the shadows where Iím planning for the reflected light.
Stapeliad, I feel like I have more freedom if I start with neutral paper, like UArt, so I can build the areas of color I want, but I do like the toned papers too and go back to that every now and then.
Shallbe, the great thing about underpainting is that if we did not get it quite right we can still go ahead and end up with a nice painting, just need to cover the mistakes. I usually donít worry about the details at first, just get the general shapes, the movement in the composition, I know itís not going to stay once I apply water or alcohol. So getting the shapes right is really my next step, for me, itís like sculpting it, rather than getting it all perfect right away, or ever
