At the end of most chapters in the first edition, there is a project to complete that helps let you know if you've understood the material presented in that chapter. For Chapter 14, beginning on page 185, the project is titled Lovely Lily.
The lesson as written is done in graphite, but I wanted color, so I used my set of 150 Prismacolor Premier colored pencils after I had achieved an acceptable outline; from that point on, I disregarded the project instructions. I did not complete the shadows or highlights, which are both important and something on which I tend to do substandard work, therefore, I'll label this a WIP... because I can still go back and correct and/or revise the drawing.
The scan you'll see here was done in May, and shows the progress on Lily that I had achieved as of the end of April, 2013. This drawing is on cheap paper, which I cut to 8X10 inches to fit a frame I have on hand. I foolishly disregarded the orientation of the paper when I began to sketch my flower, using the horizontal, or landscape orientation when I could have used the portrait orientation to better advantage, so the version you see here has had the resulting excess white space cropped off of each end for better display.
