As soon as I finished reading it I went right to my easel and worked on a landscape I had been struggling with. Much to my amazement, with the tips in your "Rules" it is much (much) improved. Landscape is definitely my weakness, so I, too, have bookmarked it and printed all the verbiage for quick reference. Thank you so much.
