A blacksmith would probably be lost but typically they ran around the interior of the walls .. Any of the extra buildings like stables, blacksmith etc ... What I would personnaly do though you would loos some of your work and you might need some other details like poser people if you can get them is drop the angle of the camera a lot and have it lookign up at the castle.. you would still see the keep looming in the distance and you could have tons of people and campfires and seige engines around it .. a few in the foreground to add details and block out some of the other areas so you don't need as much stuff S That is how I get by on a kinda slim computer .. hide stuff .. Good luck and hpe I helped some .. Just my idea
