While it might not be a novel idea to create new graphics for the Trade Workshop, as it has been done several times before, the graphics that come with this mod can be very useful. if you add them to a mod pack they will allow for more variation in town design; with a Change Name Effect they can also serve as bars, inns, taverns, large country homes, and much more.
The graphics are of a very high quality: they are all cut & paste graphics from the original game, and on most buildings you can't see where the cutting and pasting has been made! The only building where it's visible is the Mesoamerican trade workshop, where the outer stone house doesn't quite fit with the major section of the building. It doesn't look awful or anything, but it's not as perfect as the other buildings. My favourite graphic is the Eastern European trade workshop, which looks absolutely fantastic.
All in all, a quite useful and very good-looking mod!
