I am new to Morrowind (and Elder Scrolls in general) but I have installed the overhaul for Morrowind...it is fantastic! However, I am now so spoiled that the animations (creatures, combat, etc.) spoil the immersion a bit for me. I searched for "better animations" but I seem to run into dead links. Can anyone suggest any improvements?

Here's http://planetelderscrolls.gamespy.com/View.php?view=Mods.Detail&id=9020 which improves some of NPC's animation. I'm currently working on improving animations for Werewolf, and there was a project for new animations for npc's.
afaik, there are no new animations for creatures.
