Here’s a mostly completed rough draft retopo using the Retopoflow Beta: Initial face count of sculpt body alone 743,000. Retopoflow face count was 850 at this stage.

Unfortunately when I clicked Ctrl + Space on my keyboard to activate fullscreen mode I broke something and blender froze hard! I also lost my file and it somehow it may have corrupted my original save and the Retopo backup save as well because my model no longer is visible (it looks like an empty but nothing is there). In fact the sculpt is doing the same thing. I am going to try and recreate the bug to submit it. But, overall I was happy to get soo much progress on my own in such little time and effort.
