I’d add more blood, trailing as he falls. And getting on the floor, maybe dripping down the pit while Obi-Wan and Qui-Gon talk. Lightsabers might be able to cauterize a hand being cut off, but not someone being totally bisected like that. Maybe some organs come out.
I appreciate that some here want full gore while others want minimal/no gore, but maybe there’s a middle ground that can satisfy everyone: We could have blood and organs spilling from only one half of the cut, whilst the other half of the cut looks fine.
