When I go to add detail to my rough in, sometimes I just start cutting in lines and pulling out new geometry. Sometimes I start all over and use the original rough in as a reference tool. I almost hit that second point with Mesa today. I was able to get some new information that told me that my model was way to short. During the process of scaling, much of the geometry was found to have major flaws. Entire sections of walls were abandoned and I just redrew them.
You should notice some windows have been added. Also, I have the capitals on the pillars now. Those took a significant amount of time all by themselves. It was well worth it though.
This corner is essentially done now, with the exception of the upper portions, the Friezes and some detailing around the top. But it was much more progress than it looks like at a glance.
