I got the line work and the shading done today. I sat for two hours, and if I had them all to do over again, I would do it like this. It was half an hour each for the line work, and then another about half an hour each for the shading. Probably more on the flaming "S", but on average.
And the pain is not so bad. It was getting bad for the shading around where the flames are going to go, but right now, it's actually fine.
For the full progression you can go here, and check it out.
The color is scheduled for Sunday, September 14th.
