I think the snowday bard skin is really cool. But I kind disappoint of the ULT animation. It's the same as bard's other skin. Here is my idea: Instead of "Zhonya" your enemy champions, snowday bard's Ult turns enemy champions into BLUEISH PENGUINS :D . Like when you get into his magical journey you transfer into a Penguin. That will make it a perfect skin. 
Hey why šo serious,
In regards to the ult, it's kept consistent throughout all of the skins for gameplay clarity.
Can you imagine how chaotic and op that would be? An entire team turned into penguins? You couildn't tell a valuable target apart from a non-valuable target when you prepare your abilities lol. A blue stasis instead of gold is a good enough change.
a "frozen" stasis kinda okay. But become penguin? err, it's just too hard to tell if it's a stasis or polymorph.
Don't get the downvotes, it's not a bad idea just needs a bit of tweaking. A light blue, silver or maybe even white colour would be good
