I chose not to put a base underneath this model, or a bust plaque etc, while it looks pretty sitting on a desk, it also takes away a massive amount of build height you could be using to make this closer to scale size. Manually smoothed in blender with scultping tools (yes it took forever... no auto smooth on this ).New version, even smoother and in 3 pieces: http://www.thingiverse.com/thing:392804
