Then I began painting. As you can see, I did not put a whole lot of effort into clearing a workspace ahead of time:
I let the picture dry while I ate supper, then began picking out details with ink line. I think there is more to be done, but right now I'm afraid of overworking. I really need to take a break from looking at it. Tomorrow (after I get home from the day job) I'll see it with fresh eyes and perhaps be a better judge of what needs tweaking and what needs to be left alone.
