This is something that has been somewhat bothering me for a while now. The weight of the head when decapitated looks too light. It seems to almost float in the air when launched and doesn’t have the momentum you’d associate with a head its weight when coming down. It should be faster and heavier (when launched upwards: fast start, slow at peak, then fast down). It’s a small thing, but it always makes the decapitations look a bit goofy to me.
