I did, in fact, decide to re-render the entire set of Tara in her office wear with no jacket, and this set looks way better frankly. This reminds me that it's important to occasionally render things in a much higher resolution. You sometimes, not always, discover flaws in how something is setup. In this case, I increased the sub-division, the smoothing, and I also removed the Bump map as it seemed to be causing some of the strange ridges in her top. Her top also has a Normal map, so the Bump map isn't really needed anyway.
