Well, the next area went easier than before. I'm finally starting to get into a bit of a routine - learning as I go. Drew out the area in black and white and then fiddled with it a bit to get the rubbley areas. That took a bit of figuring, but, I think I'll do better next time. This is Area B, on the same level as the entrance and is intended to be the base home of a group of kobolds and their naga goddess.
Onwards and upwards. Area C should come next. Finish that up and I'm about 2/3rds done the region. Schweet.
