Just finished remodeling the tower, which entailed adding recessed windows for the upper tower structure, a recessed clock face, a recessed door-like entrance on the side of the tower, and a hoist. Here's the most recent render (w/o a bump map or much thought given to the lighting):
I suppose if I had more time, I would really make the upper tower structure look nice. Once I become more proficient in Blender, I'll move on to explore some of its more powerful features. For the time being, however, I gotta get these models cranked out and imported into Unity, so some of it's gonna be fast and a bit dirty. Maybe someday I'll take a 3D art class myself, or get some digital art students on-board who can really get some work done.
