I had no idea this was here....thanks, much vangogh....and many thanks to all who have viewed, commented and favorited the image.  It's much appreciated.  One thing I should mention, please have a look at Tanglimara's render, as well....I emailed him the terrain map and told him to 'run with it' just to see what he could come up with.....it's really a fantastic render on the original cityscape and also worth a look and comment.
