So I LOVE this Godzilla model & animations. Simply amazing, dude! If I might offer a few friendly suggestions?
-Any chance you could edit the ground-dragging tail swipe (or add a new attack) to make it more like the raised tail slap Gman does to kill the male MUTO in Godzilla 2014 (the move where he impales the Male MUTO onto some metal on a building)? That slow turn around and half second pause, then just this burst of energy where the tail slaps anything in it's way, like in the film.

-I am sure this is likely due to a rights issue with the films but I have to ask anyway... is there any chance we could get the newer/better version of Godzilla's roar from the 2014 film? The roar with the deep alligator-like bellow at the end.

-Finally, I am super surprised there isn't a biting attack, any chance you would consider adding one? Most creatures are shorter than Godzilla so I would recommend his head pointing down, maybe him even leaning down a tiny bit if you add this attack/animation.

Again.... LOVE Godzilla (especially his 2014 redesign and the new monsterverse films) and can't thank you enough for bringing him into Ark with this mod. Just added all three of your monster mods to my 'must-haves' list.
