Not playing Skyrim lately but i saw a review by Brodual on YouTube and they showed that there are no first person animations and the author recommends using immersive first person so you get the third person animations on first person, they also said that it has spear animations only on power attacks but the author reduced the cost of power attacks with spears and says that the player should use only power attacks with the spear, there is a bug that makes the skin on the head of NPCs at times have a different color compared to the body.
