Changed by rating to 5/5. The model is now versatile, but of course theres room for improvement which is always good. My suggestion is keep in mind what type of skeleton rpg model you want it to become. If you main for a fantasy rpg model, animations such as
bow, crossbow, one hand attack, two hand attack (useful for two-handed swords and hammers), unarmed attack (useful for a monk class), are very, very, useful however animations such as a dualgun wielding might add unnecessary animations. Perhaps the most logical thing would be to make a different model that supports basic melee animations and ranged animations for guns and the lot.
