Hmmm ... maybe I should explain a bit about my comment on making the hilt shorter and thicker. It's really a matter of physics rather then esthetics. The business end of the sword is massive and as such will tend to be heavy. In a fencing foil or katana it really wouldn't matter since the blades are comparatively light. Here though, the sword would have a greater tendency to twist in the grip. A shorter, thicker hilt would give better control. I was viewing it from how I'd expect this character to look in the real world. As WTB said, if it's magic then the physics be damned. Just my two cents.
