That's really a beautiful peice of work. Thanks for that.
On graphics, I took a course on Illustrator and saving graphics for
web publishing, jpegs work best becasue of file size. PDFs of vector
graphics are best for printing because of the enhanced detail. Don
smith would send both a print and a jpeg. With Illustrator a pen tool
is the best for drawing; connecting anchor points, and the the smooth
tool can be used to correct your lines.
It's a great program.
