I have been in the process of learning Blender over the past several years with the help of a couple books on my spare time. This is more or less a hobby since I do not work as a professional artist or anything close to it for a living.
This turned out to be a good final image, here is the start up where I did use Blender up to this point. I got stuck in one of the doorway entrance corners where the intersecting points of the building in the mesh model vertices could not be adjusted correctly. As a result I decided to render a png and jpg that was finished in Corel Painter.
