There are multiple different issues with the current animations. Number one being that when you eat anything (Like cooked beef) the eating animation will be shifted a little too far to the left.  

Number two is when the player is shielded and opens their inventory, the shield will bug out and look like it's going through the players head.

Number three is a mix of eating and shielding. When the player eats while holding up their shield, the food will just go inside the shield.

Number four is the bow and trident animation. Nothing is particularity wrong with them besides the fact that it looks like the player has haste when opening a door, or breaking a block.

So far that's all the animation bugs I have found so far. (Sorry for the  bad photos, I don't really know any other way to show you without exceeding the download size.)
