I have to say that this is becoming an obsession.  After two more days, for probably a total of 13 hours, I've gotten to this(doesn't look like much more, but if you can blow it up, you might see all the strokes of color.  I increased the enlargement of the canvas to 1800-3600%, so I'm covering a couple hundred pixels at a time.  I've also found that as I do a section, then correct it early on, I'm not wasting as much time.  Funny part is, I have no idea what I'm working on at 1800%-then pull back to look and say, 'oh! it's a hose!'
