@IronStylus Make Alistar Bigger
To begin with, great job to everyone involved with his update. Now that the nose ring is included it is perfect. With that in mind I believe it's the perfect opportunity to increase his size a bit for two simple reasons.
Firstly, he is a badass, muscular, long-horned cow headbutting people's faces and stuff, yet he is not as scary as he is supposed to be. I think it's a shame that Lucian is almost as tall as him and that's not the only problem. He is not big when compared to other supports either. Even Soraka doesn't seem small close to him. Braum, even though not Sion-huge, has a large model thanks to his shield. Yet Alistar looks like a blue calf. Think about it.
Secondly and most importantly, Alistar will always want to soak up as much damage as he can while CCing enemies for eternity. His ultimate highlights this even more. Making him bigger and increasing his hitbox a bit will improve his ability to block skillshots and bodyblock enemies, making him even better at protecting his allies. This will be particularly helpful at botlane.
I think you should consider the gameplay and thematic benefits of increasing his size. A furry ball of muscles is kinda funny when yelling: "Nothing can hold me back!" don't you think?
