Yes, it would look better bigger, but I wanted it to be noticeably smaller than the standard Civ units (it ought really to be tiny, but obviously that wouldn't work). It actually looks pretty good in-game (especially with the sound effects).
I thought about having the pins push through when he falls over, but the prop I was using for the pins was extremely difficult to work with and I couldn't have done it smoothly enough. You'll just have to imagine that the pins get squashed sideways when he collapses!
