So I just bought the new Bard Skin and it's awesome, even if the 'E'-penguin is a little bit too much for me. ^^
Just one little suggestion:
If you'd only change the color of the ulted units to a more white-ish look, I'd be like sooooooooooooo happy. I mean nothing fancy, not even snowflake-sprites or anything, just a few champ-popsticles.
The reason why you haven't done this already, is that you wanted the 'Zhonyas'-look, so everyone can see, that it's an untargetable unit, but imho I don't think, it would change a lot, if it's the same thing in white.
Hope you'll consider it,
